Kalksteinsfeltet ligger på sydsiden av Skjerstadfjorden like vest for ytre Kvandal og ligger på veien langs vestsiden av Skjerstad-fjorden fra Skjerstad og østover til Storvika. Kalksteinsbenker av varierende mektighet dekker store områder ute på odden. Benkene har en sydvestlig strøkretning med fall mot nordvest. Kalksteinen er utpreget benket, blågrå av farge og middels til grovkrystallingsk. Ute ved Halsodden opptrer en gråblå grovkrystallinsk kalkstein. Fire analyser som dekker en mektighet på 55 m viser følgende sammensetning: 47.50 - 49.76 % CaO, 0.23 - 1.79 % MgO, 0.73- 0.54 % oksyder (Fe2O3 + Al2O3). Prøvene er tatt på overflaten og nær sjøen, derfor antar Bøckman at friske prøver viser et høyere MgO - og CaO - innhold enn det de ovenfor nevnte gjør. En gj. Analyser fra Carstens viser 52.44% CaO, 2.98 % MgO, 0.1 uløst, 0.09 % Fe2O3, 0.002 % P og 0.002 S. Ref. K.L.Bøckman 1956: BA 437 C.W.Carstens 1946: 248.
