SEARS D.W.G. (1978) The Nature and Origin of
Meteorites (Adam Hilger Ltd., Bristol), pp. 25-26:

"Krinov (1966)* distinguishes between explosive craters, impact craters, and impact
holes. The first correspond to major craters, where essentially complete vaporization
of the meteorite occurs. Where meteorite fragments are occasionally found near such
craters, they appear to have become detached from the meteorite before impact."

"Impact craters are non-explosive but, in the former case, the meteorite is destroyed
mechanically, whereas in the latter, large specimens are usually found. For the major
Sikhote Alin fall, where more than 100 craters and holes were made, Krinov has been
able to show that the divisins may be made at 20 and 9 feet, but it is doubtful that
these figures are generally applicable."
