The unusual primitive compositions of the West Mata eruption lavas have much to tell us.

西玛塔火山喷发熔岩的不同平常的原始组分告诉我们许多秘密.

The lower degrees of mantle melting of the HT and LT2 lavas may be the result of a relatively thicker lithosphere and lower geotherm .

HT和LT2熔岩的地幔熔融程度较低，可能是与地幔柱边部的岩石圈相对较厚和地热较低有关。

It may indicate that the Martian mantle is wetter than Earth's or that younger lavas melted at different temperatures or pressures than the older basalts.

或许代表火星的地函比地球的更潮湿，或是较年轻的熔岩与较古老的玄武岩是各在不同的温度或压力下熔化。

These lavas were coeval with the volcanic activity.

这些火山岩和那次火山活动是同时期的。

Pyroclastic rocks are a kind of transitional and complex rocks between lavas and sedimentary rocks.

摘要火山碎屑岩是介于溶岩和沈积岩之间的过渡类型岩石,岩类复杂.
