The petrophysical properties of volcanic rock reservoirs in junggar basin are generally characterized by the following : the acidic lava and auto brecciated lava are the best , especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts 準噶爾盆地火山巖儲層物性一般特點是：酸性熔巖、火山角礫巖最好，特別是經后期構造運動和溶蝕作用改造后的火山角礫巖；安山巖的物性總體優于玄武巖。 |

2 both the hanging wall and the footwail rock of ore bodies are garnet biotite schist , protoliths are alkaline volcanic rocks ( tracyh andesite ) . according to characteristics of trace elements assemblages and the setting of tectonics , these alkaline volcanic rocks were derived from the lower degree melting of metasomatic and enriched mantle ( eml ) in the initial stage of middle proterozoic epoch . they strongly enriched in large ion lithophile elements ( lile ) , such as ba 2 、礦體頂、底板圍巖(石榴石黑云母片巖、鈉長黑云母片巖等)的原巖為堿性火山巖(粗面安山巖) ，相對富集大離子親石元素ba 、 cs 、 rb 、 k 、 lree及貧zr 、 sr 、 ti 、 hf 、 hree ，為早元古代末期-中元古代早期交代富集地幔低程度部分熔融所形成的堿性火山巖。 |

The analysis of the geochemical and petrologic characteristics features shows that the assemblage of volcanic rocks is the series of middle ocean ridge basalt , ocean island basalt and ocean island andesite basalt , which implies that it is the relic of the ocean crust , i . e . typical ophiolites 通過巖石特征和地球化學分析，確定了鹽邊群荒田組火山巖組合為洋脊玄武巖、洋島玄武巖、洋島安山玄武巖系列，說明這是洋殼殘片，即典型的蛇綠巖套。 |

Whereas the rocks in the ancient heavily cratered terrains were basaltic , the younger rocks of the northern lowlands resembled a more highly evolved type of lava called andesite : they contained more glass , more silica - rich minerals and fewer iron - bearing minerals 古老、充滿坑洞的地區，巖石屬于玄武巖，但北方低地較年輕的巖石卻類似一種更高度演化、稱為安山巖的熔巖：它們含有較多玻璃質、較多富矽礦物、以及較少含鐵礦物。 |

To be sure , some scientists propose that the supposed andesites are basalts masquerading as such ; a fog of water or acid could react with the minerals to create an andesitelike veneer 更有甚者，某些科學家認為這些所謂的安山巖，其實是玄武巖偽裝的；水或酸的薄霧會與礦物作用，產生安山巖似的外層。 |
