Izinyosi Zensimbi ze-Tricone Bits
1,Ukwakheka okuthambile(114-117)
Lezi zingcezu zenzelwe ukubhola ukwakheka okuthambile okufana namashali athambile, imibhede ebomvu, nobumba, okuhlala isikhathi eside kanye namazinga aphezulu okungena.
2,Ukwakheka okuthambile kuya kokuphakathi(121,124,126,134,136,137)
Lezi zingcezu zenzelwe ukubhoboza ukwakheka okufana nama-shales, i-limestone ethambile emaphakathi, i-Medium sandstone nokunye ukwakheka okunemivimbo eqinile ekhawukile.
3,Ukwakheka okuphakathi kuya kokuqinile(213,214,215,217)
Lezi zingcezu zenzelwe ukubhoboza ukwakheka okufana netshe lesandstone eliqinile, i-dolomite, kanye nokwakheka okuphukile nge-cherty streaks eqinile.
Ithebula lokuhlukaniswa kokuqina kokwakheka kanye nokukhetha okuncane
