The absence of paraffin and other oil hydrocarbons in the soil although theyare concentrated in extensive deposits in some localities, the commondistribution of plant remains through many formations that are not productivefor oil, and many other factors, seem to indicate the existence of anintermediate organic compound between the complex plant compounds and thepetroleum hydrocarbons; and much evidence points to the humus acids orassociated organic compounds, which are probably collected by surface watersand concentrated in certain areas by means of precipitation by electrolytes,which would be contained in sea water or possibly in various inland seas orlakes.
There are many present-day evidences of the association of petroleum withhumus acids. Binney, in 1912, made observations without explanations on thepeat mosses of Down Holland, England, where he found petroleum being formed bydecomposition in the presence of an infiltration of sea water. The analysis ofa typical peat will show its relationship to the humus acids underconsideration.
J. D. Haseman and others have noted the association of asphalt andhydrocarbons with the swampy, boggy areas, particularly adjacent to thesea.
Many of the rivers carry much humus acid in solution, and some tropicalrivers carry in the aggregate millions of tons of humus each year. The amountof humus is a variable factor, depending on climatic conditions, and on thesalts and alkalies present in the water, also on the density andtemperature.
