Could the chert that parallels the hammer be filled the normal fault or is it as a result of ductile deformation as it continuous with the bedding chert?
Cherts: siliceous sedimentary rocks have several origin, they may beings related to the hydrothermal fluid circulation through normal faults responsible for the formation of oceanic ridge midle
silica can result from the precipitation of micro-organisms or upper mantle differentiated.
Silica precipited from fluids will follow the avaiable pathways which in this case is a normal fault but also the layer-parallel permeability
80% confident that the silica precipitated along a brittle fault....
Thanks, this is my interesting question
By regarding the above answers, this question occured for me: If this is the silica precipitated from fluids, why no reaction rims or like this not seen in chert with it surrounding rocks?
