The lower part formed in a littoral - epeiric environment , is a series of elastic rocks , partly contains carbonate rock and metamorphic basic volcanic rocks and the upper part formed in a bathypelagic environment is a series of sediments with chert , partly contains metamorphic basic volcanic rocks 其下部為一套濱淺相碎屑巖，局部夾碳酸鹽巖、變質基性火山巖；上部為一套深水沉積巖系夾硅質巖，局部夾變質基性火山巖。

The feldspar of the reservoir sandstone in the study area consists of a higher percentage of na feldspar that of k . feldspar . the sandstone is composed of certain little rock fragments such as pyrite , mica , siltstone , mudstone , chert , and volcanic fragments 砂巖內長石由鈉長石與鉀長石組成，以鈉長石為主；巖屑由黃鐵礦、云母、粉砂質、泥質、燧石與火山巖屑構成。

The bulk of the artifacts from liang bua are simple flake tools struck from volcanic rock and chert , no more advanced than the implements made by late australopithecines and early homo 梁布亞出土的石器，大部份是以火山巖與燧石打制的簡單石片器，并不比晚期南猿人與早期人屬物種制作的石器先進。

The thin - beded siliceous - rocks include chert and depositional quartz with textures of oolite and pebble 矽質巖包括燧石和沈積石英巖，呈薄層狀產出，沈積石英巖具鮞狀、礫狀結構。

Carbonate rocks are predominantly composed of intra - clastic dolostone , chert dolostone and sand - bearing dolostone 碳酸鹽巖以內碎屑白云巖、燧石白云兒和含砂白云巖為主。

Thus we can better understand the deformation of chert in a highly fluid form . 這樣我們就能更好地理解燧石在高度流體狀態時的變形情況。
