The second episode is here re-defined as the "real" Linzizong volcanic successions that comprise, from bottom to top, Dianzhong, Nianbo and Pana Formations.

根据原始定义，后者才是"真正的"林子宗火山岩，并可由老至年轻分为典中组、年波组及帕那组等三个火山地层单元。

The Pana volcanic rocks of the Linzizong Group in Zhaxue area, Linzhou County, Tibet are mainly composed of rhyolitictrachy lavas and volcanoclastic rocks.

分布于西藏林周县扎雪地区的林子宗群帕那组火山岩，主要由流纹质-粗安质熔岩和火山碎屑岩组成。

The quartz-monzonite porphyry intrusived in the Pre-Ordovician Songduo Group and Carboniferous-Permian Laigu Formation, unconformably covered by the volcanic rocks of Pana Formation.

石英二长斑岩侵入于前奥陶纪松多岩群和石炭-二叠系来姑组中，并被帕那组火山岩呈火山沉积不整合覆盖。

Its geochemical characteristics (14.55% of Al2O3 8.78% of K2O+Na2O, 5.77% of K2O, K2O/Na2O=2.07) suggest that the Pana Formation volcanic rocks belong to highAl, highK calcalkalineshoshonite series.

岩石总体上反映出高Al高K的特点，Al2O3的质量分数平均为14.55%，K2O+Na2O的质量分数平均为8.78%，K2O质量分数平均为。77%，K2O/Na2O比值平均为2.07，显示了高钾钙碱性-钾玄质火山岩的特征。

Those formed during the flare-up period, i.e., the Pana Formation, however, show significant geochemical variations from low-K tholeiitic through calc-alkaline to shoshonitic compositions coupled with increasing enrichment in LREEs. Therefore, the volcanic successions are divided into four suites, namely, calc-alkaline suite, low-K suite, high-REE suite and shoshonitic suite.

在大喷发时期产生的火山岩最不均质，组成从低钾拉斑质、钙碱质变化到钾玄质，并且呈现不同程度的轻稀土元素富集，我们据此可将本期林子宗火山岩区分为钙碱质系列（calc-alkaline suite）、低钾系列（low-K suite）、高稀土系列（high-REE suite）和钾玄系列四类。

These layered rocks measure only 10 centimeters (4 inches) tall and are thought to be either volcanic ash deposits or sediments carried by water or wind. Data from the panoramic camera's near-infrared, blue and green filters were combined to create this approximate, true-color image.

关于这些层状岩石，有的测量数据约10厘米(4英寸)，相对高一点的地方，目前被认为或许是火山灰的沉淀物，抑或是风干沉积后的河床岩石层，当然这一切在被证实之前仍仅仅是猜测。

She did not dream of the volcanic convulsions of love, its scorching heat and sterile wastes of parch ed ashes

她从未梦想过火山爆发大地抽搐式的爱情，从未想到过它的熊熊烈焰，它的破坏作用，它能烧成一片片焦土。
