摘要

Isli and Tislit, the Moroccan “Romeo and Juliette” according to a popular legend gave their name to a twin lakes in Imilchil. There we show evidences that these two lakes are impact craters. The proof as follow: 1) the fragments of iron meteorites found on both sides of Isli and Tislit lakes belong to the same parent meteorite and siderite type;2) the sedimentary formations which are almost tabular in the area of the lakes become tilted with a centripetal sloping all around and towards Isli lake;3) the circular shape of the Tislit lake is similar to that of the Isli lake;4) the impact breccias found on the south of the Isli lake contain shocked quartz crystals;5) the radial fractures of high pressure affect some sedimentary beds. All these observations give evidence of the presence of an impact crater due to the fall of meteorites.
