Abstract：Based on the study of a chronosequence of soils, developed from basalts erupted in different geological times, in the northern Hainan island, the variation of soil properties with soil age increasing in its development has been discussed quantitatively. The results show that such soil properties as solum and B horizon thickness, redness rating (RR), w(REE), w(Ba)/w(Nb), w(Fed)/w(Fet),w(Fed), w(Feo)/w(Fed), silica-alumina molecular ratio and silica-sesquioxide ratio of soils, frequency dependent susceptibility, etc. are definitely correlative to the soil ages. The statistical equations between soil properties and ages have been determined according to pedological principles. When found in the same or similar soil-forming environment and regions, relative soil age and soil development degree could be inferred by soil properties which could also be evaluated by soil ages to research rate of soil formation depending on those equations.
