Abstract

Organska teorija nastanka nafte izražava kako se nafta formirala iz nekad živućih organizama. Proces se sastoji od nekoliko faza. Dijageneze, katageneze te metageneze. Svaki od ovih procesa odvija se na karakterističnim tlakovima i temperaturama duboku u sedimentu. Pristalice abiogene teorije uglavnom su ruski znanstvenici uz nekoliko izuzetaka poput Thomasa Golda. Prema ovoj teoriji nafte i ostalih ugljikovodika ima u izobilju u unutrašnjosti Zemlje ta kao takvi još dugo vremena neće nestati. Ugljen nastaje karbonizacijom biljnog materijala. Proces je podijeljen u dva stupnja dijagenezu i metamorfozu. Nastanak i tip ugljena ovisi o niz čimbenika. Prema stupnju karbonizacije razlikujemo treset, mrki ugljen, smeđi ugljen te antracit.

Abstract (english)

The organic theory of the formation of oil expresses how oil is formed from once living organisms. The process consists of several stages. Diagenesis, katagenesis and methagenesis. Each of these processes takes place under characteristic pressur and temperatures deep in the sediment. Supporters of abiogenic theory are mainly Russian scientists with a few exceptions like Thomas Gold. According to this theory oil and other hydrocarbons are abundant in the Earth's interior that as such for a long time will not fade. Coal is produced by carbonization of plant material. The process is divided into two stages of diagenesis and metamorphosis. The origin and type of coal depends on a number of factors. According to the stage of carbonation we can distinguish peat, lignite, brown coal and anthracite.
