Annotation	The Botovskaya Cave which is developed in the Angarsko-Lensky Plateau ca 700 km N of Irkutsk in Ordovician limestones, is an example of a horizontal two-dimensional maze with a total length of explored passages exceeding 60 km. The cave system is located 310 m above the Lena River level. The detrital cave fills differ both in mineral magnetic and mineralogical parameters. Two depositional events could be observed. The older sediments consist of sands showing low magnetic susceptibility (MS) and low radioactivity values and are derived from weathered sandy Cambrian bedrocks. The sediments were transported by horizontally running water entering the cave system when the relief was peneplained, probably during the Late Tertiary. The overlying cave deposits, predominantly clays and sandy clays, reveal higher MS and radioactivity values and were transported vertically to the cave passages during rain or meltwater events.
