Abstract:
I feltet følges kalken i < 300 m, mens mektigheten er ukjent. Samme horisont 1 km mot NØ? I såfall 40 m mektig. I kalkstein finnes kvarts i korn og knoller Avbygging til 10-20 m dyp gir flere millioner tonn. Analysene er av prøver tatt over 8-10 m mektighet. CaO: 47.4-54.2%, MgO: 4.55-0.52%, Gl.tap: 39.1- 42.95%, SiO2: 7.89-2.0%.
