安徽省杨庄铁矿是近年来在钟姑山矿田新发现的又一大型铁矿床,位于宁芜盆地南段钟姑山复背斜的次级褶皱向阳向斜构造的北转折端,矿体主要赋存于徐家山组与闪长(玢)岩的内外接触带、三叠系徐家山组地层中及闪长(玢)岩内部,整体走向NW,倾... 安徽省杨庄铁矿是近年来在钟姑山矿田新发现的又一大型铁矿床,位于宁芜盆地南段钟姑山复背斜的次级褶皱向阳向斜构造的北转折端,矿体主要赋存于徐家山组与闪长(玢)岩的内外接触带、三叠系徐家山组地层中及闪长(玢)岩内部,整体走向NW,倾向SW,局部倾向SE,倾角变化较大,总体呈似层状、层状、透镜状产出,局部具分支复合、膨大收缩,尖灭再现等特征,矿石以磁铁矿为主,次为(假象)赤铁矿矿石,矿石结构以他形-半自形微细粒结构为主,矿石构造以浸染状-稠密浸染状构造为主,矿床成因应属气化-热液交代为主的充填-接触交代型铁矿床,明显有别于已有的凤凰山(白象山)式、姑山式铁矿床,应为新亚式"杨庄式玢岩铁矿"。该新亚式的提出,丰富了"玢岩铁矿"模式。 展开更多

Wano, spoken by about 7,000 native speakers, is a Papuan language of Trans-New Guinea Phylum, Dani-Kwerba Stock, which is found in the interior of Papua of the regency of Puncak Jaya. The language is closely related to Dani, Walak, and Nggem. It is an SOV language typology that has a complex morphological system. Four spatial dimensions are morphosyntactically coded in elevative deixis, which are steepness/non-steepness distinction, proximity/distality distinction, adverbial/attributive expressions, and vertical/horizontal plane. This paper discusses the grammatical operation of a set of two-term system: ei "up" and ou "down" that serves as the basic forms for the elevational deixis in Wano. 展开更多
