Traprock is a type of volcanic rock that forms from the rapid cooling of lava. It is typically dark in color and has a fine-grained texture. Traprock is often rich in minerals like basalt and andesite, making it a valuable resource in construction and landscaping. This rock is commonly used as aggregate in concrete and asphalt, as well as for road base material. Its durability and resistance to weathering make it an ideal choice for various engineering projects. Additionally, traprock formations can create unique landscapes, contributing to the geological diversity of regions where they are found.
