Abstract
Flint Clay in the Coal-barren Triassic of the Sydney Basin, Australia
F. C. Loughnan
ABSTRACT
Claystones that are similar in composition, texture and structure to some of the flint clays of the Olive Hill area, Kentucky, form a persistent marker bed in the coal-barren Triassic Narrabeen Group of the Sydney basin.
The underlying sediments consist of a relatively thick succession of red-brown claystones, or "chocolate shales," which, apart from the presence of abundant hematite, possess the same mineralogical and textural features as the flint clay.
The "chocolate 'shales" are believed to represent a transported lateritic clay that was deposited in a nonreducing' environment. The flint clay probably resulted from a change to reducing conditions within the depositional basin.
