Overlying the rocks of the Horton Group are shallow marine to evaporite deposits of the Windsor Group, comprising a basal stromatolitic laminated dolostone layer overlain by a sporadically developed massive gypsum layer, up to 120 m thick, which is in turn overlain by fossiliferous carbonate rocks and fine-grained clastic rocks typical of a sabkha-mudflat environment (Geldsetzer 1977; Hamblin 1989a).
The well was drilled to a total depth of 5,255 metres (subsea), but did not encounter clastic reservoirs.
The second hole is underway approximately 350 metres to the north and is currently above the low-angle fault in Mississippian clastic rocks, which the Company's geologists believe could act as a "cap rock" by ponding mineralizing fluids beneath the low-angle fault at this location.
Sedimentary clastic dikes are formed due to filling of open fractures with allogenic detrital material either on land or in sub-bottom layers of water bodies.
Also, experimental samples showed that trampling of the lake marl substrate compacted the sediment, ordered fine clastic material and sometimes produced sub-horizontal cracks.
1971) recognises 2 principal units in these sediments: deposits of coarse clastic sediments and limestone.
Three reservoir systems are present in the basin with fair to good reservoir parameters (both clastic sediments and carbonates)
