来到民权县科研新区,一条条宽阔整洁的柏油马路,一排排规划统一的楼房,特别是那色彩鲜艳的新型水泥彩瓦,打破了长久以来"秦砖汉瓦"传统的青灰色基调,使人为之一亮.近两年来,民权县强力整治粘土砖瓦窑厂,加快发展新型墙体材料,结合本县实际,坚持"禁实"与"推新"双管齐下,"堵"与"疏"双措并举,大力推广新型建材,从而推动了新型建材的迅猛发展,有效保护了耕地. 相似文献

Asphalts distributed widely in the Silurian sandstones of the Tarim Basin include dry asphalt, soft asphalt and heavy oil.
These asphaltic sandstones underwent multi-episodic sedimentary and tectonic events, and their occurrence is diverse and complex,
being mixed with normal oil usually. So far, very little work has been done on the asphaltic sandstone origin and hydrocarbon
charging ages. After detailed study on the Silurian sandstones, the following highlights were obtained from the analytical
results: distribution of the mixed asphalt, heavy oil and normal oil in the Silurian sandstones is the result of multi-stage
hydrocarbon charging from the Lower Paleozoic marine source rocks; the characters of asphalts formed from oils of different
charging ages are of difference; the most important process constraining the asphaltic sandstone origin is thought to be biodegradation.
This paper was financially supported by funds of Petroleum & Natural Gas Exploration in the Tarim Basin from the “State 9th
Five-Year Plan Period” Key Scientific Project (No. 96-111). 相似文献
