Potassium jarosite
WebWhile the pyrite and jarosite are secondary minerals formed during diagenesis, the carbonaceous material of the wall appears to be primary. This is consistent with the occurrence of pyrite in partially pyritized specimens (Figure 5b,d,j,l ), which suggests pyrite nucleation followed the decay of the organic wall from both the exterior and interior of the … WebReference: Jensen, M.
