Answer
Based on the given information, the volcanic structure shown in the case of the Buddhist monastery Taung Kalat in Myanmar is a volcanic neck or volcanic plug. A volcanic neck forms when magma solidifies within the conduit of a volcano, and over time, the surrounding rock is eroded away, leaving behind a steep-sided, columnar mass of solidified magma. In this case, the ancient volcano has been worn away, and only the solidified magma in the conduit remains, forming a prominent rock structure on which the monastery is situated.
