The development features of reservoir space are different in different lithofacies belts. In a word, around volcanicvent is favorable reservoir development position.
不同岩相带储集空间的发育特征不同，火山通道周围是有利储集层发育区。

The scientists determined that the depression was a volcanicvent, and the bright ring around it was pyroclastic, remnants of lava that had been spewed outward, much like a volcanic fountain on Earth.
They have both the flooding and the intrusive lithofacies but also have the volcanic and the volcano vent lithofacies and the lithology is mainly the middle acidic intrusive rocks.
