For the first time polymorph of silica in the form of white colored pebbles of spherical and elongated shapes has been detected at Crater Lake and ejecta, on a large scale which was investigated in a course of research to understand its characteristic features. Elemental composition and oxides of these pebbles through XRF analysis showed Silica (SiO₂), to be 97.985 mass % with negligible quantities of CaO, Fe₂O₃, SO₃, Al₂O₃, and Cr₂O₃. Physicochemical analysis carried out showed that these pebbles are not related to salinity or alkalinity. The high content of SiO₂ (Silica), showed that it is a polymorph of silica. Findings of silica pebbles at Lonar Crater have not been reported by earlier workers. The formation of silica pebbles is related to Lake water. Formation of silica pebbles and the presence of diatoms in the lake water indicate that the lake water contains a high percentage of SiO₂, the source of which is unknown. Pebbles are generally found near river beds or near the seashores. For which lotic water body is responsible. These pebbles contain a high percentage of CaO. Findings of large quantity of silica pebbles at Lonar crater in which SiO₂ is 98% mass, this is unusual because white pebbles containing high percentage of CaO is known, but white pebbles containing high percentage of silica (SiO₂) is unknown and has not been reported from any of the volcanic eruption sites nor has it been reported from any of the meteorite impact crater sites either, also these silica pebbles are not found in large quantity on the earth surface. Silica pebbles being a rich source of silica and found in abundance here, an industry of making glass beads may have flourished here in the 14th century. This part has not been explored in the past and is a preliminary investigation, this paper reports the first-hand information of findings of silica pebbles, a polymorph of silica and to put on record the findings. A standardless approach has been adopted.
