We recognize four types of coexisting calcite precipitates, including calcite cement in dilation breccia, calcite in striated groove morphology, calcite gouge associated with hydraulic fracturing and pressure solution, and calcite coating of the fault surface. Overall, the calcite cement and striations are more closely to the host rock. Journal of Geochemical Exploration, v. By Yoav Avni. Need an account?
While the uppermost morphology of calcite coating 78—70 ka shows no evidence for postprecipitation deformation Fig.
Pol- either within complex veinlet networks e. Samples from the calcite coating layer are suggested to and with calcite-filled dilation veins from the same site Nuriel et al. This approach requires a better understanding B of the precipitation mechanisms associated with the formation of fault striations, and the temporal relationships between faulting, dissolution, F6 F7 F1 F1 F23 fluid mobilization, and calcite precipitation.
