16. Which of the following lists of foliation textures is in the correct order from highest metamorphic grade to lowest metamorphic grade?

A. Gneiss texture, schistose texture, phyllitic texture, rock cleavage
B. Rock cleavage, phyllitic texture, schistose texture, gneissic texture
C. Non-foliation, rock cleavage, gneissic texture, hornfels texture

The order of foliation textures from highest to lowest metamorphic grade is: Gneiss texture, schistose texture, phyllitic texture, rock cleavage. Foliation is a characteristic of metamorphic rocks due to the physical or chemical changes they undergo in heat and pressure. The highest grade is represented by Gneiss, followed by Schistose, Phyllitic and the lowest grade is rock cleavage.

Explanation:

The correct order of foliation textures from highest metamorphic grade to lowest metamorphic grade is: Gneiss texture, schistose texture, phyllitic texture, rock cleavage. This order reflects the increasing metamorphism or alteration under heat and pressure that these rocks have experienced.

Foliation is a common property of metamorphic rocks, resulting from the physical or chemical alterations that they undergo under extreme heat and pressure. During these transformations, minerals can be reoriented, giving the rocks a layered or banded appearance.

In metamorphic rocks, the highest grade is represented by Gneiss, which has been subjected to the highest level of heat and pressure. This is followed by Schistose, then Phyllitic, and finally, the lowest grade is signified by rock cleavage.
