Zitsulo za Zitsulo za Tricone
1, Maonekedwe ofewa (114-117)
Zidutswazi zidapangidwa kuti zibowole zofewa kwambiri monga ma shale ofewa, mabedi ofiira, ndi dongo, zolimba kwambiri komanso zolowera kwambiri.
2, Zofewa mpaka zapakatikati (121,124,126,134,136,137)
Ma bitswa adapangidwa kuti azibowola mapangidwe monga ma shale, miyala yamchere yofewa yapakatikati, miyala yamchenga Wapakati ndi mapangidwe ena okhala ndi mizere yolimba yokhazikika.
3,Zapakatikati mpaka zolimba (213,214,215,217)
Zidutswazi zidapangidwa kuti zibowole ngati miyala yolimba ya mchenga, dolomite, ndi mapangidwe osweka okhala ndi mizere yolimba ya cherty.
