ABSTRACT: 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.
