2021-11-12  This paper presents a new depositional model for the Amasiri Sandstone of the southern Benue Trough, Nigeria. Variants of facies and facies relationships suggesting fluvial, storm, and sediment gravity processes gave rise to controversies in the interpretation of environments of deposition for the formation. However, newly exposed sections in the quarries

Limestone: Characteristics, Uses And Problem GSA

2016-10-13  Limestone subjected to exterior exposures deteriorates due to weathering or the natural effects of wind, rain, and thermal change. Limestone is extremely durable. It does, however, absorb water and, since it is a carbonate rock, it is highly reactive when exposed to acids or even mildly acidic rain water, and it can suffer substantial ...
