Speleothem deposits developed in caves and tunnels of Deccan-Trap basalts, Maharashtra, India

Calcite speleothems composed of stalactites of about 1/2 cm to 1 1/2 cm in length and stalagmites of approximately 15 cm are found in the ancient caves and tunnels in the Deccan-Trap basalts. Thin-section analysis reveals that they dominantly consist of clay-rich micrite, microspar, or sparry calcite layers. These layers are either finely laminated and planar, or irregular and exhibit sutured contacts.
