Sebagian besar dolin terbentuk oleh proses pelapukan kimia batuan karbonat di formasi karst, keruntuhan, atau proses sufusi.<ref name="bgs">{{cite web|url=http://www.bgs.ac.uk/mendips/caveskarst/karst_3.htm|title=Caves and karst – dolines and sinkholes|publisher=British Geological Survey}}</ref> Dolin biasanya berbentuk melingkar, ukuran dan kedalamannya bervariasi, mulai dari puluhan hingga ratusan meter. Bentuk dolin juga bervariasi, ada yang berbentuk serupa mangkuk dengan tepian tanah, ada juga yang berbentuk [[ngarai]] sempit dengan tebing dari lapisan batuan dasar yang tersingkap. Dolin dapat terbentuk secara bertahap atau tiba-tiba, dan ditemukan di seluruh belahan dunia.<ref name=":1">{{cite web|last=Kohl|first=Martin|year=2001|title=Subsidence and sinkholes in East Tennessee.
