Colloquially known as "volcanic bombs", this specimen is an impressive example of a mantle xenolith, featuring a rounded nodule of olivine encased in fine-grained black basalt. Sourced from the volcanic regions where such specimens are common, the green hues are predominantly olivine, with the possibility of discovering bright green chrome diopside crystals. The black basalt outer layer adds contrast, and some "bombs" even display a teardrop shape, formed as the lava solidified mid-air. This piece showcases dunite, or peridotite, ultramafic rocks rich in olivine—renowned for their vitreous luster and striking, conchoidal fracture. Ideal for collectors, this specimen offers a unique glimpse into the geological processes that shape our planet. Its varied colors and textures, combined with its geological significance, make it an excellent addition to any mineralogical collection or display.

This specimen comes from the collection of Peter Tarassoff, a prominent figure in mineralogy, particularly known for his work at Mont Saint-Hilaire (MSH). His diligent collecting and examination efforts have led him to be the first to identify at least 35 species and discover 12 new species, not only at MSH but also at other alkaline localities. Dubbed the "Dean" of Mont Saint-Hilaire collectors, Peter was honoured with the naming of the new species petarasite in 1980. He has authored or co-authored numerous mineralogical articles and has been a member of the Mineralogical Association of Canada since 1964 and the Mineralogical Society of America for over 30 years. Additionally, Peter has volunteered at the Redpath Museum for the past 21 years. In recognition of his significant contributions to mineralogy, Dr. Peter Tarassoff was awarded the 2017 Pinch Medal by the Mineralogical Association of Canada.

Peter's dedication to systematic collecting, curating his collection, and maintaining an archive of detailed historical and scientific information has greatly benefited the mineral sciences community both in Canada and globally. All specimens from this collection come with the original P. Tarassoff collection label.
