他們發現，從凝灰巖中流出的水中鈾含量反常。The mine zone is sandwiched between an overlying block of flows, pillow lavas and minor pyroclastics, and underlying agglomerates, tuffs, and more massive diabase bodies.
含礦帶夾在上覆的巖流、枕狀巖流和少量火山碎屑巖塊與下伏的集塊巖、凝灰巖和塊狀輝綠巖體之間。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，然後依次是花崗閃長巖，流紋斑巖及玄武巖。The machadodorp tuff and agglomerate, which is higher-lying than the ongeluck lave, is known only from the eastern transvaal.
層位較昂格魯克巖流為高的馬卻多多普凝灰巖及集塊巖，只見于德蘭士瓦東部。The hydrothermal breccia and karst in the beiya area are divided into 4 types and zones, including : sedimentary tuff and breccia induced by hydrothermal explosion and sedimentation on land surface ; hydrothermal sedimentary conglomerate and gas - explosive ejecting breccia related to sedimentation in and collapsing of some shallow karst caves ; netted hydotherma1 limcstone breccia and hydrothermal explosive breccia pipe related to hydrofracturing, corrosion and explosion in the hydrothermal channels ; and yellow granular limestone formed by simmering and alteration in the deep heated water reservoir
北衙地區熱水角礫巖和熱水巖溶可分為4種類型和層次，即地表相爆發沉積作用形成的沉積凝灰角礫巖、熱水沉積鮞狀灰巖與鈣華膠結角礫巖；與近地表洞穴沉積和垮塌作用有關的熱水沉積礫巖和汽爆射流角礫巖；與熱水通道相蝕裂和爆破角礫化作用有關的網路狀灰巖角礫巖筒和熱水隱爆角礫巖筒；深部相熱水浸煮蝕變灰巖。The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid, meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud, the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks
同時，受熱流體活動的影響，熱流體對火山碎屑巖具有一定改造作用，如在安山質巖屑凝灰巖中，斜長石絹雲母化、火山巖巖屑綠泥石化明顯；在凝灰質泥巖中，熱流體對圍巖中有機碳具有明顯的「催熟」加熱作用，微量元素則出現異常現象。This paper deals with high fluid concrete in which high strength ceramsite made from shale was used as coarse aggregate. effects of cement content, water - cement ratio, sand percentage, mineral admixture, grading and pretreatment of lightweight aggregate on compressive strength and workability of high fluid structural lightweight aggregate concrete have been studied. the rules of water absorption of high strength lightweight aggregate under different pressure and effects on uniformity of high fluid structural lightweight aggregate concrete have been studied too
本文採用高強頁巖陶粒，摻加高效減水劑配製大流動性結構輕集料混凝土，討論了水泥用量、水灰比、砂率、礦物摻料及輕集料的級配和預濕方式對大流動性結構輕集料混凝土強度和工作性的影響；系統研究了高強陶粒在常壓和壓力下的吸水規律；研究了影響大流動性結構輕集料混凝土勻質性的因素，提出了解決大流動性結構輕集料混凝土分層離析的具體措施。分享友人
