sanidine

基本解釋

In order to determine the time sequence of recent eruption in Tianchi volcano, the TL thermal-stability has been investigated for pumice and sanidine phenocryst within the volcanics.
為厘定天池火山近代噴發(fā)的時(shí)序,對(duì)堿流巖中的浮巖和透長(zhǎng)石斑晶進(jìn)行了熱釋光(TL)信號(hào)熱穩(wěn)定性研究。
This will causedifferent ascent velocities and then different diffusion rates of volatile in magma. The change of the pH2o in magmas during their ascenting triggers the changes of the stability of phlologopite,leucite and sanidine.
從而引起巖漿在上升過(guò)程中所含揮發(fā)分發(fā)生散失的程度有差異，造成PH2o的變化，而這正是控制金云母、透長(zhǎng)石及白榴石穩(wěn)定性及變化的主要物理參數(shù)。
Studies on Gyirong Basin Pliocene sediments showed that the nest composition of the sediments were smectite, kaolinite, chlorite, illite, sanidine, quartz, calcite and less gypsum.
對(duì)吉隆盆地中上新世沉積物的研究表明，沉積物的礦物成分主要由黏土礦物伊利石、高嶺石、綠泥石、蒙脫石以及長(zhǎng)石、石英、方解石及少量的石膏等組成。

high sanidine
高溫型透長(zhǎng)石

an alkali feldspar that is a high-temperature glassy form of orthoclase in flat, tabular crystals, found in lavas and dykes. Formula: KAlSi3O8

透長(zhǎng)石
The mineral sequence of crystallization from early to late is ilmenite. hedenbergite. fayalite. sodian sanidine, quartz and arfvedsonite.3. The alkaline rhyolitic lava at Late Qixiangzhan Stage belongs to comendites of alkaline series, and its compositon is similar to the Tianwenfeng comenditic pumice.
礦物由早到晚的結(jié)晶順序依次是：鈦鐵礦、鈣鐵輝石、鐵橄欖石、鈉透長(zhǎng)石、石英和鈉鐵閃石；3．氣象站期晚期堿流質(zhì)熔巖是堿性系列的鈉閃堿流巖，與天文峰期堿流質(zhì)浮巖成分相似。
