Bonchev received many academic honours and was also proficient in gemmology and geoarcheology. \r\n\r\nFleischer (1958) compared the x-ray pattern of bonchevite to those of galenobismutite and \"bismuthinite\" and noted their similarities. Nechelyustov and Lebedev (1967) described a \"bonchevite\" from Kara-Oba, Kazakhstan with x-ray and chemical data similar to Bulgarian bonchevite. Craig (1967) discovered that phases in the PbS-Bi2S system exsolved to a mixture of \"bismuthinite\" and galenobismutite. Kupcik et al. (1969) studied topotype bonchevite and found their specimen was a mixture of galenobismutite and a member of the andorite group. Bonev (1982) identified the unknown Kara-Oba mineral as lillianite. Birch and Mumme (1985) also studied a mineral they collected \"from a vein north of Nahrechen\" and they concluded their specimen was pekoite - \"No inclusions were observed.\" Birch and Mumme (1985) concluded that a near equal mixture of pekoite and galenobismuthite would yield the reported chemical composition reported for bonchevite and by extension that the mixture was possibly a homogeneous phase that exsolved into the two phases that were consistently observed in synthetic and natural specimens.","2025-08-11 12:14:32",[],[],[],[],[],8,[33,37,41,45,49,54,58,63],{"id":34,"year":35,"html":36,"doi":8},523140,1958,"Fleischer, M.
