| 1. | The mine zone is sandwiched between an overlying block of flows, pillow lavas and minor pyroclastics, and underlying agglomerates, tuffs, and more massive diabase bodies . 含矿带夹在上覆的岩流、枕状岩流和少量火山碎屑岩块与下伏的集块岩、凝灰岩和块状辉绿岩体之间。 |
| 2. | Holocene tephra deposits in the northern okinawa trough 冲绳海槽北部的全新世火山碎屑沉积 |
| 3. | Pyroclastic rocks pyroclasts 火山碎屑岩 |
| 4. | 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。 |
| 5. | As bad as the pyroclastic flows are , the ash injected into the atmosphere can have even more far - reaching consequences 如同火山碎屑流般凶恶,喷发进入大气层的火山灰甚至会造成更深远的影响。 |
| 6. | Despite of this , the field geology and the character of pyroclastic rocks remain the basis of the petrogenesis of pyroclasic rocks 尽管这样,野外地质和火山碎屑岩的岩性特徵,仍是火山碎屑岩成因研究的基础。 |
| 7. | Existence of charcoal fragments in sedimentary basaltic volcanoclastic rock and its implication in geology , in longtan formation of southwesten guizhou 黔西南地区龙潭组玄武质火山碎屑岩中木炭碎屑的存在及地质意义 |
| 8. | As the land above the magma chamber collapses , immense gray clouds called pyroclastic flows burst out horizontally all around the caldera 当岩浆库上方的陆地崩陷,称为火山碎屑流的巨大灰色云雾,会突然由火山臼的周围向外水平散开。 |
| 9. | On the basis of the past schemes , new classifications of pyroclasts and the petrographic as well as the petrogenetic classification of pyroclastic rocks are proposed in this paper 中国学者提出的火山碎屑岩分类时间较早,有自己特色,在一定的范围得到了应用。 |
| 10. | A great number of lherzolite xenoliths occurs within the volcanic clastics characterized by terrigenous central type eruption at tianyang , jiudouyang and yingfenglin of qingtongyang , of southern leizhou peninsula 摘要雷州半岛南部田洋、九斗洋及青桐洋的英峰岭等陆相中心式喷发的火山碎屑岩中,分布有大量的二辉橄榄岩包体。 |
