Bragin meteorite. Refers to the type of iron-stone meteorites, or pallasite (pallasite P MG). Place of meteorite fall- Belarus, Gomel region. First discovered in 1807 by Kutovsky, village Kaporenki (now Bragin district) in Belorus. In 1927 by Kolyban village in the same area 2 more samples were found.  In 1937, half a mile o the south-east from Crook, at the depth of 120 cm , the largest of the samples was found with a total weight of 270 kg.

Chemical composition: dominating elements iron (Fe) 50% and nickel (Ni) 3%, other elements: olivine, analogue of terrestrial hrizalite.

Coordinates of fall: latitude - 51 `30'N; longitude 030 '24' E.

Sikhote-Alin meteorite. Refers to the type of iron meteorites.  An Iron IIB- OgH meteorite. Place of meteorite fall - Russia,Primorsky Krai, Sikhote-Alin mountains, Sikhote-Alin reserve (387,284 ha). Date of fall: February 12th 1947, 10:38 am. Though meteoroid  fall took place in the morning , according to the witnesses, it was seemed “brighter than the sun”,” throwing shadows”  and “making one`s eyes almost blind”. Meteorite research nowadays is facing difficulties because the area of fall is a natural reserve where rare animal species such as amur tiger and sable are being protected.

Chemical composition: iron (Fe) 93.32 %, nickel (Ni) 5.71 %, cobalt (Co) 0.48%, copper (CU) 0.011%, phosphorus (P)- 0.28%.

Approximate coordinates of fall: latitude - 46 9,600 N, longitude - 134 39,200 E. Fall area from 25 to 35 square kilometers.

Dronino meteorite. Refers to the type of iron meteorites (iron ungrouped). Place of meteorite fall - Russia, Kasimov district of Ryazan region. Discovered in Aril 2003. Total meteorite mass about 2800 kg.

Chemical composition: iron (Fe) 95 %, nickel (Ni) 5%.

Coordinates of fall: latitude - 54° 44' 48"N; longitude - 41° 25' 18"E.

Sejmchan meteorite. Refers to the type of iron-stone meteorites, type IIE or  pallasite. Place of meteorite fall - Russia, Magadan region. Found in 1967.

Tektites- minerals formed by the melting of terrestrial rocks due to the explosion during the fall of meteorites. Contain about 0,5 % of cosmogenic substances. Tektites are composed of silicon dioxide (SiO2) , concentration lying between 65-80%- and aluminium oxide Al2O3, the microcavity filled with a mixture of carbon dioxide CO2, hydrogen H_methane CH4 and rare gases. Tektites are for example Libyan glass, moldavite, etc.
