There may be as many as four groups of tilas in Sylhet - Chhatak group, Sylhet group, Dhaka-Dakshin (South) group and Beanibazar group. Important characteristics of these tilas are shown in the following table.

There are also some scattered tilas in Sylhet, such as, Kuleral Tila (226m), Dupi Tila (100m), Khasia Tila (108m), and Chatal Tila (>130m). The tilas are composed of Pleistocene clays and sands over a coarse ferruginous sand stones, mottled sandy clays and shales of Dupi Tila Formation. Tilas were once under dense forest cover and now very little of that cover is left. Most of the tilas have come under tea cultivation. [Mohd Shamsul Alam]
