UN_5047_2_A_rocks_10.jpgChert with soft sediment deformation features
UN_5047_2_A_rocks_11.jpgPossibly primary erosional channel in chert layers
UN_5047_2_A_rocks_12.jpgSoft sediment deformation with brittle fracturing and erosional channels cutting previous sedimentary layers
UN_5047_2_A_rocks_13.jpgWell plucked creamy white chert, an extreme brittle response to the drilling action.
UN_5047_2_A_rocks_14.jpgWell-developed sulphide laden erosional channel cutting previous soft sediment, now chert.
UN_5047_2_A_rocks_15.jpgAn expanded view of the channels and reworked channels with BMS laden infilling, mostly pyrite.
UN_5047_2_A_rocks_16.jpgSmall scale brittle fracturing in zebra white chert
UN_5047_2_A_coring_1.jpgWhat happens when you try and weld a drill bit into chert.... a seriously burnt in bit.
UN_5047_2_A_coring_2.jpgWhat happens when you try and weld a drill bit into chert.... a seriously burnt in bit.
UN_5047_2_A_coring_3.jpgGordon examining the burnt in bit.
UN_5047_2_A_coring_4.jpgMasi getting up close and personal with some chert
UN_5047_2_A_coring_5.jpgThe distinction between TNW (left) and NQ ( Right) drill bit size is adequately illustrated ...
UN_5047_2_A_coring_6.jpgNote a core orientation marking which is possible with NQ but no core orientation equipment is available for TNW core size
UN_5047_2_A_rocks_17.jpgInteresting soft sediment cuspate pressure deformation on left, brittle fracturing in centre and right.
UN_5047_2_A_rocks_18.jpgDisrupted layer fragments now re-welded in chert

UN_5047_2_A_rocks_22.jpgDisrupted layers
UN_5047_2_A_rocks_23.jpgThe chert contains excellent sedimentary and silicification structures. Rip up clasts, dismembered layers, brittle fracturing and rewelded reconstituted layered now chert.
