英文摘要	Analyses of trace elements of the lower palaeozoic carbonate rock strata in beijing show that the contents of as, hg, f increase from primary carbonate rocks to weathered carbonate rocks and from primary carbonate rocks to the soil coexisting with carbonate rocks, but the distribution regularity of s is not obvious. in the whole weathered stages, the sorption of as is mainly affected by fe2o3. in soil fe2o3 is also the main affecting factor of hg enrichment. the main existing forms of hg in primary carbonate rocks should simply be physical adsorption, coprecipitation and false isomorphous form between surface of carbonate rock and hg. in soil the enrichment of f has little relationship with sulfides and fe2o3. in primary carbonate rocks, f is mainly absorbed by sulfides and clay minerals, etc. weathered samples have closer genetic relationships with primary carbonate rocks. this also implies that weathered carbonate rocks have the close existing forms to that of primary carbonate rocks. in primary carbonate rocks fes2 and fes are the main forms of s, and sulfides have fixation effect on some heavy metals, whereas in weathered carbonate rocks and soil the fixation effect is weakened.
