| 4. | Geochemical characteristics and paleogeographic significance of early carboniferous cherts at the nongba section in the gengma area , southwestern yunnan 滇西南耿马地区弄巴剖面早石炭世硅质岩的地球化学特征及古地理意义 |
| 5. | Ore type primarily contains the copper sand scraps slilica rock or contain the copper gravel scraps silica rock , a little amount powder sand sericite callys type copper silver mine and dolomie type copper silver mine 矿石类型主要有含铜砂屑硅质岩或含铜砾屑硅质岩刑,少量粉砂质绢云母板岩型铜银矿石及白云岩型铜银矿石。 |
| 6. | The geochemistry characteristic of fuchsia radiolarian silicalite indicates that they deposited in the of edge of oceanic basin near the continental margin , not the typical caontinental margin environment 从硅质岩的地球化学特征表现来看,紫红色放射虫硅质岩部分不是形成于典型的大陆边缘环境中,而是形成于近大陆边缘的洋盆边缘环境。 |
| 7. | The lower member of typical ophiolite suit is exposed at outsides of the qimanyuter ophiolite melange and in between , there distribute the basalt , deep sea limestone and silicalites . these different litho - members contact to each other with ductile shear zones 带内蛇绿岩套下部单元出露于两侧,玄武岩和相关的深水灰岩、硅质岩等分布于中部,各单元间均以韧性剪切带接触。 |
| 8. | The immediate host siliceous rocks of typical deposits ( jinya , gaolong ) are of hydrothermal sedimentary origin . gold ore bodies are layer - like and generally concordant with their host rocks . abundant relict synsedimentary fabrics are preserved in the ores 典型矿床(金牙、高龙)中的含矿硅质岩属热水沉积岩,矿体形态主要为与地层整合的层状和似层状,矿石具有大量同生沉积的标型组构。 |
| 9. | The stratum , deposited in nongba which in eastern part of gengma area and composed by sandstone , mudstone and silicate and tuff interlayers , was named by former man as nanpihe formation and papai formation , and their age were later permian and early triassic respectively 耿马弄巴地区出露一套以砂泥质岩为主体夹硅质岩、凝灰岩的地层,前人将它命名为南皮河组和怕拍组,并分别定名为晚二叠世和早三叠世。 |
