沃尔彻陨石坑(Woltjer)是月球背面北部高纬度区的一座大撞击坑,约形成于38-32亿年前的晚雨海世[1],其名称取自荷兰天文学家扬·沃尔切尔(Jan Woltjer,1891年-1946年),1970年被国际天文学联合会正式批准接受。

描述

[编辑]

该陨坑北侧与蒙戈尔费埃环形山相接壤、东面靠近斯托列托夫陨石坑库利克环形山施内勒尔环形山则分别坐落在它的东南和西南面[2]。该陨坑中心月面坐标44°52′N 159°50′W / 44.87°N 159.83°W / 44.87; -159.83,直径44.50公里[3],深度约2.27公里[1]

沃尔彻陨石坑是一座较月背大部分陨石坑都要年轻的撞击坑,坑壁略有磨损,边缘轮廓完整清晰,外观呈圆形状,但它的实际地质龄仍非常悠久,其反照率与周边地形相一致,缺乏射纹系统。部分内侧壁已坍塌,并沿南侧坑底形成岩屑堆。沃尔彻陨石坑坑壁最大高出周边地形1070米[1],内部容积约1529立方千米[1]。坑内表面地形坎坷,分布有一座中央峰和二道低矮的山脊。它与北面毗连的蒙戈尔费埃环形山及卫星坑蒙戈尔费埃 P蒙戈尔费埃 J一道,构成一幅形似猫爪印的外观。
