volcanic cone

A mass of pyrolite xenolith ( such as peridotite andpyroxenide) and high-pressure mineral megacrysts ( such as anorthoclase, augite and kaersutite) are found in cone sheets and BS volcanic rocks.

锥状岩席和BS火山岩包含有大量的上地幔岩石包体（橄榄岩类和辉石岩类）和高压矿物巨晶（歪长石、普通辉石和钛闪石）。

The third class includes taphrogenic and alluvial plain, tilted and alluvial plain, volcanic cone, fault valley, intruded rock hills and hog-back highland.

三级构造地貌有六种类型，即断陷冲积平原、掀斜冲积平原、火山锥、断层谷、侵入岩丘陵和拱曲高地。

A volcanic cone is a conical mountain or hill built up of material from volcanic eruptions.
