About The White Ironstone China Association. With the 1980 publication of A Look At White Ironstone followed by A Second Look At White Ironstone in 1985, both by Jean Wetherbee, the interest in white ironstone exploded as collectors searched for the mid to late 19th century ware detailed in both books. A small group of white ironstone collectors from the New England states and New York met ...

Apr 01, 2021 Ironstone is a marine biochemical sedimentary rock with syndepositional Fe enrichment that has long been viewed as a geologic curio. It is widespread in the Silurian Clinton Group and coeval strata across the Appalachian Foreland Basin the Clinton ironstones, where it has been the focus of extensive historical study aimed at elucidating its enigmatic origin.

In this paper, we examined the REE geochemistry of ironstone deposits that developed on the top parts of the lateritic soil of the Northern Oman Mountains during the early Cretaceous time. This lateritic soil developed on a layered gabbro or serpentinized harzburgite of the Semail ophiolite. The main objective of this study is to reconstruct the conditions and the paleo-environment of ...
