Sažetak

Dokazano je da se optimizovanom stupnjevitom degradacijom kerogena alkalnim permanganatom mogu otkriti očuvane specifične prekursorske strukture u makromolekularnim, heterogenim matricama kerogena, čime se doprinosi osvetljavanju puteva geneze kerogena i definisanju njegovog porekla. U ovom radu ispitivan je kerogen škriljca Pumpherston. Dobijeni su dokazi da je ovaj kerogen mešovitog porekla. Nađeno je da sadrži nasleđene postojane specifične biomakromolekularne algalne strukture (algaenane) alge B. braunii A i B, kao i otporne biomakromolekularne sastojke kutikula kontinentalneflore (kutane). Na osnovu rezultata istraživanja može se pretpostaviti da je kerogen pamferstonskog škriljca, ili bar neki njegovi delovi, postao mehanizmom selektivnog očuvanja.

Ključne reči
