Regional Metamorphism within a Creationist Framework:

2017-6-28  The “classical” model for regional metamorphic zones presupposes elevated temperatures and pressures due to deep burial and deformation/tectonic forces over large areas over millions of years—an apparent insurmountable hurdle for the creationist framework. One diagnostic metamorphic mineral is garnet, and variations in its composition have long been studied as an indicator of metamorphic grade conditions. Such compositional variations that have been detected between and within grains in the same rock strata are usually explained in terms of cationic fractionation with changing temperature during specific continuous reactions involving elemental distribution patterns in the rock matrix around the crystallizing garnet. Garnet compositions are also said to correlate with their metamorphic

REGIONAL METAMORPHISM WITHIN A CREATIONIST

Indeed, the realization that the “classical” zones of progressive regional metamorphism are potentially only a reflection of variations in original sedimentation, as can be demonstrated in continental shelf depositional facies today, provides creationists with a potential scientifically satisfying explanation of regional metamorphism within ...

Towards a Creationist Explanation of Regional

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 catastrophic erosion and sedimentation, deep burial and rapid deformation/tectonics during the Flood.

The Metamorphic Earth - scienceonline.pan.pl

The definition of “metamorphism” embraces numerous mineral, structural, and textural transformations of solid rock. The processes occur under high temperature and/or pressure, although there are certain exceptions. Researchers distinguish four main categories of metamorphism: dynamic, contact (thermal), shock (impact), and regional.
