Tektites originate in what metamorphic environment?
a. low pressure and high temperature associated with volcanism
b. high temperatures associated with meteorite impacts
c. very high pressures and temperatures associated with deep subduction
d. high temperatures and shearing stresses in an oceanic-crust transform fault

B. High temperatures associated with meteorite impacts

Explanation:

Tektites are a grave sized black, green , brown and grey, natural glass ejected from the terrestrial debris and range in size from a few millimeters to centimeters. And have a homogeneous composition and extremely low water contents and lack microscopic crystals. Are formed by the hypervelocity of the meteoritic impacts near the terrestrial sediments and the ricks were either melted, combined and sediment. And after the impact of the collusion of the crater, they formed small bodes of the molten material.
