24) The time equivalence of strata is determined by _______.
A) correlation of unusual lithologies
B) correlation of key beds
C) correlation of fossils
D) lateral tracing
E) superposition
Solution:
The time equivalence of strata is determined by: correlation of fossils
The strata is defined as the layers of rocks. The chemical, heat, and pressure chnages the layers into the rocks. Hence, it is determined by the correlation of fossils.

Groundwater at a temperature of 250C flows through strata containing abundant fluorite (CaF2) mineralization and becomes saturated with respect to that mineral. The equilibrium solubility product, Ksp, for this reaction is 10^-10.4. a) Calculate the concentrations of Ca2+ and F- once the water has reached saturation with respect to fluorite assuming that prior to entering the mineralized strata the water had an ionic strength of less than 10-5 mol/L and contained negligible Ca2+ and negligible F-. For this part of...
