For the question that I think you are asking I think
the primary reference is Kyte (1998). Kyte (1998) stated:

"The fossil meteorite from DSDP Hole 576 appears to be
from (1) a chondritic meteorite with (2) significant
amounts of metal and sulphide (4-8%), (3) large
inclusions [>200 um] of mafic minerals that also
contained metal, and (4) 30-60% fine-grained matrix. The
known meteorite groups that best fit these criteria
could be the CV, CO, and CR carbonaceous chondrites."

Tertiary boundary. Nature, vol. 396, pp. 237-239.

This web page stated:

"Dr. Frank Kyte of UCLA, who disovered the meteorite
fragment in the K-T boundary sediments from the
Pacific Ocean (Kerr, 1996; Kyte, 1998), believes that
the bolide that carved-out the Chicxulub crater in
the Yucutan Peninsula of Mexico was of the chondritic
type."
