Sandatlas

This process will lead to the formation of high grade metamorphic rock gneiss and gneissose fabric which can be described as a poorly developed schistosity Sometimes schist is imagined to contain at least 50 of elongated minerals 1 but in many cases the distinction between these rocks is just based on the qualitative assessment of a geologist describing the rocks in the field.

On Silica Activity and Serpentinization

Silica activity in igneous rocks Silica activity has long been used in the classification of igneous rocks Carmichael et al 1974 even though it has rarely been assigned a numerical value.Thus it is helpful to compare the silica activity in serpentinites with that of the well known igneous buffers .With decreasing silica activity the normative minerals in igneous rocks are
