"In 1957 WMC began its search for a sediment hosted copper deposit in the vast Proterozoic of Australia, a search which would last 19 years and cost $12 million in today's money terms. Our perception at the time dictated that the search be concentrated where there were signs of copper in favourable host rocks - shales like those of the African Copperbelt or lavas like those of Michigan. Limited vision took us to the remote Warburton Ranges, and to the Fortesque Group in the Pilbara. Only when science opened our eyes to the importance of looking for copper where events may have sourced copper did improved vision enable us to see the potential of the Stuart Shelf in South Australia, where tectonics and geophysics subsequently guided us to Australia's greatest ore deposit at Olympic Dam." p232.

The Hamersley Province of Western Australia comprises a thick succession (up to 5-6 km) of largely volcanic rocks (Fortescue Group) overlain by a 2.5 km thick succession dominated by banded iron-formation units (Hamersley Group) (e.g. Harmsworth et al., 1990). The province contains an early Proterozoic foreland fold-and-thrust belt that hosts ten percent of known world reserves of iron ore. Renewed company interest in extending ore reserves requires knowledge of the subsurface structural geology, which will be gained by incorporating surface geological data with gravity, magnetic and seismic data. Data from two multi-channel seismic profiles obtained in 1997 (Figure 1) will constrain structural sections through the region, and gravity and magnetic measurements will be used to discriminate between possible alternative subsurface sections. Balanced structural sections across the fold-and-thrust belt will form the basis for an integrated model of the structural evolution of the Hamersley Province.

The longer of the two seismic lines, situated approximately 100 km west of Newman, begins in gently folded late Archaean to early Proterozoic Hamersley Group rocks close to the undeformed foreland and continues south into a fold belt dominated at all scales by north-verging asymmetric folds. The southern margin of the fold belt is bounded by a major normal fault that brings the younger sedimentary rocks of the late Paleoproterozoic Bresnahan Basin into contact with dolerites of the late Archaean upper Fortescue Group.
...
A shorter line, 20 km east of Newman, runs approximately 40 km north-south from Hamersley Group rocks that progressively become more intensely deformed to the south before crossing into the Sylvania Inlier (Figure 1). This Archaean granite-greenstone terrain is juxtaposed against the younger rocks of the Hamersley and Fortescue Group, and the boundary is interpreted as a south-dipping fault contact involving over-thrusting of basement during formation of the fold-and-thrust belt (Tyler & Thorne, 1990; Tyler, 1991). Geophysical data along this seismic line provide important constraints for modelling the geometry of this important boundary.

4. Mingar Dome, Pilbara Craton, Western Australia

Field relations, Landsat-5-Thematic Mapper multispectral images
and geophysical data were examined in connection with the
near-perfectly circular 80 km-diameter large Mingar Dome, western
Pilbara Craton, north western Western Australia, with the aim of
elucidating its origin. The dome consists of Fortescue Group (2.76
Ga) mafic volcanics and minor felsic volcanics and sediments
unconformably overlying core inliers of granite (3.24 Ga),
migmatite and amphibolite exposed by the Fortescue River at the
center of the structure. Local pseudotachylite microbreccia vein
systems occur immediately below the basal unconformity of the
Fortescue Group on the Fortescue River, consisting of angular
quartz grains and deformed feldspar and containing granitic
fragments from the surrounding basement. No penetrative
deformation lamella diagnostic of high velocity shock were
observed, and the veins were possibly triggered by earthquakes. No
direct evidence has been observed for a meteoritic impact
connection of the Mingar Dome. A spin-off of the present study has
been the Landsat-5-TM correlation and identification of a range of
Fortescue Group and Hamersley Group volcanic and sedimentary rock
types, allowing spectral fingerprinting of a range of lithological
types, including separation of carbonates, shales, iron formations
and a range of volcanic rock types using band ratios and principal
components.

Project Description
Palaeogeography, sedimentology and tectonics of the Fortescue Group, southern Hamersley Province, Western Australia.
The project aims to provide a palaeo-reconstruction of the southern margin of the Pilbara Craton approximately 2765 Million years ago when the Fortescue Group was deposited, unconformably, on the granite-greenstone terrane. This will be achieved by:
Applying basin analysis techniques to the 3 lowermost formations of the Fortescue Group (Bellary Formation, Mount Roe Basalt and Hardey Formation) in order to determine distribution and facies.

Palaeocurrent analysis and petrography of the Hardey Formation (quartz-rich sandstone) to determine provenance..
Geochemistry of the Hardey Formation to determine provenance and combined with points (1) & (2) will set up a tectonic discrimination diagram for Archaean sandstones..
Geochemistry (major and trace element) of basalt flows from the Bellary Formation and Mount Roe Basalt to determine tectonic setting..
Provide an age for the Bellary Formation using zircons from a tuffaceous unit. Method of analysis will be by SHRIMP..

Brief Summary of results to date
Regional mapping of the Bellary Formation at 1:15,000 scale has identified a series of basalt flows intercalated with fluvial and lacustrine sediments .The base of the Bellary Formation is not seen, but is assumed to be unconformable with the Archaean Granite-Greenstone terrane.Basalt flows 1-4metres thick, with autobrecciated flow tops, at the base of the formation are overlain by upward fining turbidites (Tb-Td). Flute Casts within the turbidites indicate a source region to the east.A poorly sorted conglomerate, with well rounded boulders of granite, chert, banded chert and basalt overlies the turbidites but is not laterally continuous.Above the turbidites and conglomerate are more basalt flows with coarse, but well sorted, quartzose sandstones and very fine siliceous mudstones. The thickness of the Bellary Formation is approximately 400 metres. Preliminary geochemistry results indicate that the basalts have calc-alkaline to tholeiitic affinities.
Conformably above the Bellary Formation is the Mount Roe Basalt, found only on the Bellary and Rocklea Domes. Two new locations of the Mount Roe Basalt have been identified on the Rocklea Dome. The distribution of the basalt on this dome may have been controlled by NNE trending growth faults, active during deposition of the lower Fortescue Group. Geochemistry results are similar to the Bellary Formation with calc-alkaline to tholeiitic affinities and LREE enrichment. More results are pending.
The Hardey Formation is an extensive quartz-rich sandstone with localised conglomerates at the base. The base of the Hardey Formation is either unconformable with the basement or disconformable with the Mount Roe Basalt Restored palaeocurrent results from trough cross beds, parting lineations, flute casts and ripples indicate a source region from the east, north east. The average quartz composition from the Milli Milli and Rocklea Domes is 70-72 % with the remaining 30 ­28 % made up by plagioclase and K-feldspar. The Hardey Formation on the Bellary Dome has a higher component of quartz (83%) which is similar to the percentage of quartz in the Bellary Formation (82%). The percentage of heavy minerals is very low, and restricted to zircon, titanite, apatite and Fe-oxide minerals. These results suggest that the source the Hardey Formation was most likely of granitic origin.
Initial palaegeographic reconstructions suggest that the lower Fortescue Group was deposited in a non-marine environment such as an alluvial braid plane, at the onset of rifting approximately 2.76 Billion years ago. Normal faults active during the rifting formed graben and half-grabens which acted as local depocentres for the Bellary and Mount Roe Basalt. The disconformity between the Mount Roe Basalt and Hardey Formation indicates a pause in the rifting, followed by erosion of a granitic source to the east and deposition of a fluvial sandstone and silts. Conformably above the Hardey Formation are pillow basalts, basalts, volcanoclastic sediments and komatiites of the upper Fortescue Group.

Rebecca (1940) is the classic Hitchcock gothic thriller and a compelling romance-mystery.
An expensively-produced film by David O. Selznick (following his recent success with Gone With The Wind (1939)), it was Hitchcock's first American film,
although it retained distinctly British characteristics.
This film won for the director his first and only Best Picture Academy Award Oscar, beating out strong competition in 1940 from The Grapes of Wrath,
The Great Dictator, The Philadelphia Story, and Hitchcock's own Foreign Correspondent.
The film also won an Academy Award for Cinematography, and was nominated in nine other categories, including Best Director.
The film's screenplay is based on Daphne du Maurier's novel of the same name.

The Carrier

Starring Gregory Fortescue, Stevie Lee, N Paul Silverman, Steve Dixon, N Paul Silverman
Allegorical, Stephen King›inspired indie, shot in Michigan, about mysterious dissolving disease striking a small town. Unknown to all, disease is carried by a persecuted young man. Well-acted, inexpensive film is confident and aware of its own absurdities, though it falters at the very end. (1988, Rated NR)
