关于在山东地台东南部山区工作所见到的几种泉,分别叙述如下: 1.喀斯特裂隙——溶洞泉: 位于黄山NW80°方向距黄山约400米处,泉露标高海拔200米。出露地层为中寒武纪致密块状石灰岩与白垩纪凝灰质砂、页岩层。接触处,凝灰质砂、页岩风化成低凹之地,致密灰岩直接露于地表形成陡崖。灰岩中两组节理发育,其产状为:倾向SW260∠70°,倾向NE5°∠23°,沿着这两组节理均有泉水涌出。裂隙——溶洞泉较大者直径10—15厘米,
About several kinds of springs seen in the southeastern mountainous area of Shandong platform, they are described as follows: 1. Karst fissure - dissolved cave spring: Located about 400 meters away from Huangshan in the direction of NW80 ° of Huangshan Mountain, the spring dew elevation is 200 meters. The exposed formations are mid-Cambrian tight massive limestone and Cretaceous tuffaceous sand and shale. Contact, tuffaceous sand, shale weathering into the low ground, dense limestone directly exposed to the surface to form a cliff. Two sets of joints developed in the limestone. The occurrences are as follows: the tendency is SW260 ° 70 ° and the tendency NE5 ° ∠23 °. The spring water gushes out along the two sets of joints. Fissure - the largest cave springs 10-15 cm in diameter,
