Four major rock types are found within the reserve . from the oldest to the youngest , they are the tuffs with volcanic bombs , granodiorites , porphyritic rhyolites and basaltic dykes , respectively . geomorphologically , the marine reserve has typical exposed rocky shore of south - easterly - directed capes and headlands in hong kong 鶴咀海岸保護區內可以找到四種主要巖石種類,以巖石形成的年代計算,最古老的是火山爆發形成的凝灰巖,然后依次是花崗閃長巖,流紋斑巖及玄武巖。

The upper cretaceous jingzhushan formation in the biru basin , xizang consists of a succession of coarse - grained elastic rocks in the alluvial fan - fan delta depositional system , intercalated with intermediate - acidic volcanic rocks including dacite , andesite , quartz trachyandesite and rhyolite 摘要上白堊統競柱山組為一套沖積扇扇三角洲沉積體系的粗碎屑巖,間夾由英安巖、安山巖、石英粗安巖和流紋巖組成的中酸性火山巖。

From the spatiotemporal distribution of the volcanics of kalagang frn . and tiaohu fm . , we can see that there are not only eruptive facies such as rhyolite but also effusion facies such as andesite , basalt and shallow intrusive rock inside the basin 從三塘湖盆地下二疊統卡拉崗組及中二疊統條湖組火山巖的時空分布特征可以看出,研究區既發育噴發相的流紋巖,又發育溢流相的玄武巖、安山巖及淺成侵入巖。

You should note how the enhanced potassium values over the rhyolite plug within the area of basalts become progressively less obvious with increasing broader smoothing . 你應當注意的是,處于玄武巖區內的流紋巖巖頸上較高的鉀濃度值,隨著平滑程度的增大而逐漸變得不明顯了。
