Porphyroblastic garnet 1 (20–30% by mode) contains a folded internal schistosity defined by trails of biotite 1, quartz and sillimanite 1 (Fig. 3a). S 2 is defined by biotite 2 –kyanite that refracts around garnet 1 (Fig. 3b). A second generation leucosome (quartz–K-feldspar 2) cuts S 1.

Towards a Creationist Explanation of Regional Metamorphism ...

This leads to a proposal for a creationist explanation of regional metamorphism. Two major events within the creationist framework of earth history are capable of producing regionally metamorphosed terrains—the tectonism, catastrophic erosion and sedimentation during the formation of dry land on Day Three of Creation Week, and the ...
