Abstract
Summary: The heavy minerals in the sandstones of the Middle Limestone Group in Northumberland include four ubiquitous species, namely garnet, rutile, tourmaline and zircon. With the aid of a scanning electron microscope, evidence of abrasion, corrosion and secondary growth on these grains was recognised. Garnet shows corrosion features only. Rutile is of both detrital and authigenic origin. Tourmaline displays abrasion and growth features, whilst zircon is a very stable constituent both mechanically and chemically. The form and surface textures of authigenic pyrite are also recorded.This publication has 9 references indexed in Scilit:
