Under which of the following metamorphic conditions, would jade most likely form? O Along a high pressure fault zone environment. O Along a subduction zone where volcanic activity has taken place. Low temperature and low pressures. This is typical of sediments that have been deeply buried, similar to those found in submarine canyons. O Near an igneous intrusion. This is where t pressures are very high and jade can form. the temperatures and in submarine very highExplanation / Answer

The heat and pressure conditions in Subduction Zone favor the formation of Jade.
23) Quartzite
Quartz sandstone is converted to quartzite by the process of heating and applying pressure.
