Abstract : A simple method of modeling, utilizing the cumulation principle, ha been succe sfully mploy o r pro uce lu ar ring formations The method consists in the dropping of solid bodies (pieces of metal, stone, slag) onto a viscous surface (tar, cement, gypsum) at the moment of hardening or set ing. A DROP STRIKING THE STILL LIQUID SURFACE FORMS A HOLE INTO WHICH THE LIQUID RUSHES. The collision of liquid particles filling the hole causes a small cumulative droplet to be ejected upward a high ki etic en rgy to a con iderable eight T ES CO UCTED UNDER NORMAL ATMOSPHERIC PRESSURE (760 mm Hg) and in a rarefied atmosphere (300 mm Hg) yielded positive results. OLID MO L OF YPIC L LUNAR RI G FORMATIONS WITH SURROUNDING WALL, STEEP INTERNAL AND GENTLE EXTERNAL SLOPES, CONCAVE BOTTOM, CENTRAL PEAK LOWER THAN THE SURROUNDING WALL, RAYS, CLEFTS, ETC. WERE OBTAINED E I E IO OF THE CIRQUE MODELS ARE DIRECTLY PROPORTIONAL TO THE MAGNITUDES OF THE CUMULATIVE EFFECTS WHICH, IN TURN, ARE DETERMINED BY THE VELOCITY AND MASS OF THE SOLID BODIES INCIDENT ON THE HARDENING MEDIUM.
