问题 选择题

读地质构造图,回答下列问题。

小题1:根据甲图判断下列说法正确的是

A.A处的岩石名称可能是大理岩

B.在A处采煤可能出现的事故是透水事故

C.C处的岩石名称可能是大理岩

D.在B处采煤可能出现的事故是瓦斯爆炸小题2:据乙图分析判断下列关于该地区地质结构及地貌说法正确的是(岩层的埋藏深度:岩层距离地面的垂直距离,可以用来帮助恢复岩层的地形)

A.①③⑤⑦处为向斜成谷

B.②④⑥处为背斜成山

C.⑧处是褶皱

D.⑥处地貌的形成主要是由外力作用导致的

答案

小题1:C

小题2:D

题目分析:

小题1:据图可知,C处岩石处于岩浆上升路径上,且附近为石灰岩,则石灰岩很可能在岩浆高温高压条件下发生变质,形成大理岩;A处背斜成谷,背斜是良好的储油储气构造,因此容易发生瓦斯爆炸;B处为向斜成山,向斜是良好的储水构造,因此容易发生透水事故。

小题2:读图可知①③⑤⑦均为谷地,地下岩层向上拱起一般为背斜构造,地表为谷地则为背斜被侵蚀成谷,根据这两个条件①、⑦岩层上弯其顶部受张力被侵蚀成了背斜谷地;②④⑥处为山地,但②⑥为向斜山,只有④处为背斜山;⑧处岩层不连续且下降,说明断裂下陷,地质构造为断层;⑤在地表形成断层谷。
