Stalactite - Wikipedia

A stalactite (UK: / ˈ s t æ l ə k t aɪ t /, US: / s t ə ˈ l æ k t aɪ t /; from the Greek stalasso, (σταλάσσω), "to drip", and meaning "that which drips") is a type of formation that hangs from the ceiling of caves, hot springs, or manmade structures such as bridges and mines.

University of Minnesota’s Mineral Pages: Calcite

Calcite and aragonite also form most of the cave decoration found in caverns present within the carbonate rock units across the southern part of this region. In Upper Midwest caves, calcite is the primary mineral component of cave formations such as stalactites and stalagmites, although many of the more delicate cave features are composed of aragonite. On a more domestic front, calcite is the ...
