  • Three volumes of SAM samples (SAM1-SAM4789) exist. They represent the work of FW Anderson in the 1950s and 1960s. All samples were re-registered into other datasets. They are predominantly from the Cretaceous and Tertiary. Sample number, fossil type, locality and geological details are given, including borehole name and depth where appropriate.

  • Whole rock and microanalytical geochemistry data from rocks collected from the Colorado Mineral Belt, Thirtynine Mile volcanic area, Cripple Creek gold deposit (& environs) and other volcanic and intrusive bodies of the Pikes PEak - Gunnison area of Colorado.

  • Registers of microfossil analyses carried out by FW Anderson in London mainly during the 1950s and 1960s, but includes older collections,notably those of Davis (1935) and Burrows (1948). Specimens recorded are mainly ostracods, but include some foraminifera and some charophytes and holothurians. Sample number, locality/borehole, specimen identifications, remarks, cross referencing to the SAM and other data sets are given. The set is arranged: MIK(M) 1-4483 in 41 volumes on Mesozoic (predominantly) ostracods MIK(T) 1-1590 in 11 volumes, Tertiary foraminifera MIK( C) 1-400 in 5 volumes, Carboniferous ostracods MIK (J) 1-1219 in 8 volumes Jurassic microfossils (few identifications) MIK(K) 1-677 in 7 volumes Cretaceous microfossils (identifications patchy) MIK(J)F, MIK(K)F and MIK(T)F are small foreign collections.
