Heritage Type
Igneous and Metamorphic Petrology.
Value
Geoheritage site of national significant.
Description
This site showcases the calcareous shale and limestone lenses within the Kroh Formation, characterized by dark gray rocks with a significant carbonate content. These rocks exhibit remarkable hardness, fine-grained texture, and distinct light gray bands infused with silica.
Deposited during the Ordovician-Silurian period, roughly 443–419 million years ago, these formations originated in the depths of ancient oceans. Over time, metamorphism transformed the rocks into hornfels, while the limestone lenses metamorphosed into marble.
One of the noteworthy geological features observed here is the presence of recumbent folds and calcite-filled joints, contributing to its aesthetically pleasing appearance.
Significant
This site holds national scientific value representing the upper calc-silicate facies within the Kroh Formation experienced contact metamorphism as a result of granite intrusion.
Other Heritage
Its geological uniqueness coupled with its aesthetic allure makes it an ideal location for public recreation and education.
