This study was for comparisons of transitional element concentrations from the two different soil, serpentinite(SP) and granite area(GR), Kwangcheon and Hongseong area. Soils were collected by soil depths (10, 20 and 30cm) from the sites selected In the plant species(coniferous and deciduous species). In the soils, the SP was high in the Cr, Mn, Fe, Co, Ni and Zn concentrations, while the GR was high in the Cu, As, Sc and V. With the soil depths, the elements had high solubility, such as Cr, Co and Ni concentrations, were high in the SP, while the other elements were not clear. For the both species, the SP was high in the root and bolebark, while in the GR, not clear. Coniferous species in the same soil types, was higher than the deciduous In most elements. The more with increasing ages, the more with element accumulation in most plant parts except leaves. Comparisons between the soils and plant species, in the case of the element contents within the soils, the plant species in the same sites was similar trend. especially, clear in the SP

Rare earth contents(REE) were analysed for the plants, M. sinensis. A. vulgaris and R. crataegitolius, from two different soils serpentine area consisting of serpentinite(SP) and non-serpentine area, containing amphibole schist(AS) of Gapyeong area, and were compared with soils and host rocks. The AS were high with the differences of several times in the top soils, and with the differences of several to ten times in the host rocks relative to the SP. In the same area, the SP were high in the soil, but the rocks for the AS. In the plants, the A. vulgaris were high, but low in the R. crataegitolius. Root parts were higher than the upper parts. Differences between the upper and root parts were big in the SP rather than the AS, and were big in the R. crataegitolius, but small in the M. sinensis. Among the parts of the plants, high elements were shown in the R. crataegitolius of the SP, and the A. vulgaris and M. sinensis of the AS. In the correlation coefficients, most of the REE showed positive relationships among the element pairs, especially high positive correlation coefficients in the upper parts of the SP.Differences of the soils and plants(average) were smalle in the M. sinensis and big in the R. crataegitolius. In the upper parts. contents of the A. vulgaris were close to the soils while the R. crataegitolius showed large discrepancies with the soils. In the root parts, contents of the A. vulgaris showed discrepancies with the soils regardless of soil types, but close in the R. crataegitolius of the SP and M. sinensis of the AS.

Heavy metal concentrations in rocks and soils from serpentinite(SP) and in plants (Pinus densiflora: PD and Pinus rigida: PR) were examined at Baekdong mine in Hongsung, Chungnam. Parent rocks were compared with amphibole schist(AS) and gneiss(GN) and plants divided the above grounds and roots were examined, respectively. In rocks, Ni, Cr, Co, Fe concentrations in SP were higher than those in AS and GN. The concentrations of top soils had the similar differences to their rocks; especially Ni, Cr, Co, Fe concentrations were the highest in SP, Zn and Sc concentrations, however, were the highest in AS. Average Ni, Cr, Co, Au, As, Sb, W concentrations of PD were the highest in SP and especially Ni, Cr, Co concentrations were accorded with changes of rocks and top soils. Zn and Sc concentrations in AS were higher and Fe and Mo concentrations in GN were higher than those in SP. Compared with two plants in the same serpentinite sites, most elements of PR were higher than those of PD. Therefore, these suggested PR absorbed much heavy metal than PD. Most element concentrations of roots in two plants and three rocks were higher than those of the above ground. Relative ratios (average plant concentration/soil concentration) of Ni, Cr, Co, Zn, Sc, Fe in AS and GN were higher than those of SP. Especially, relative ratios of most elements except Zn in GN were the highest.

High-pressure amphibolite-facies rocks with serpentinized ultramafic rocks occur in the Gyeonggi Massif. Ultramafic rocks occur as lenses within Precambrian granite gneiss, which showing dominantly tectonic lines of NNE directions as well as east extensional area of the chinese collision belt between south and north China block(\ulcorner). This study regionally makes a comparative study of ultramafic rocks in the western part of the Gyeonggi Massif in Korea. (omitted)

Heavy metal elements were analysed to assess degrees of heavy metal contents for the plants, M. sinensis, A. vulgaris and G. oldhamiana, from the Baekdong serpentine area within the western part of Chungnam. The area was divided into two sites ; serpentine area (SP, consisting of serpentinite, SP) and non-serpentine area (NSP, containing amphibole schist, AS and gneiss, GN). Their host rocks(R) and top soils(S) were also collected from the each site. As the results of the study, the plants contain high concentration of Ni Cr, Co in the SP and Fe, Zn in the AS and GN. Plants from the AS of the NSP contain mainly high content in the most of elements. Averages of Ni, Co and Cr for the plants decreased in the order of SP, AS and GN. In the total element contents, M. sinensis and A. vulgaris decreased in the order of Fe > Ni or Cr > Zn > Co > As > Sc within the SP and in the order of Fe > Zn > Cr > Ni, within the GN. Comparing among the parts of plants, root parts were higher in the most of elements than the above grounds. In the relative element ratios of plants collected from the SP and GN (SP/GN) M. sinensis was lower than A. vulgaris in the most of elements, suggesting that the M. sinenis shows low absorption within the infertile serpentine soil and high absorption within the fertile gneiss soil. In the element contents of the top soils and their host rocks, the SP shows higher Ni, Co and Cr contents than the others. Their total contents decreased from SP to AS and GN, suggesting that the soils reflect the composition of their host rocks. Total element contents of the SP decreased in the order of Fe> Cr or Ni> Co> Zn> As> Sc and, for the GN, in the order of Fe> Zn> Cr> Ni> Co or Sc, respectively. In the relative element ratios, R/S of the SP decreased in the order of Cr> As> Fe> Sc> Co> Ni> Zn and for the GN, in the order of Sc> Fe> Ni> Zn> Cr> Co. Comparing with plants within the each site, their top soils were higher than the plants in the most of elements. and their increase and decrease trends for each element are similar. Differences of element contents between the top soils and plants decreased in the order of SP, AS and GN. Plants of the GN were moi-e similar to their soils than those of the others, suggesting that each plant species show different absorptions within the different soils. Comparing with the plants of GN, higher Ni, Co, Cr contents within those of the SP and their survival within the infertile serpentine soil suggest that the M. sinensis, A vulgaris and G. oldhamiana may be the tolerance species in the serpentine soil. Comparisons with the upper crust show that M. sinensis, and A. vulgaris within the SP show high Hi and Cr contents. suggestive of hyperaccumulation. Upper results with the previous studies for the contaminated soils developed as parent materials with the serpentinites suggest additional studies for ecological behaviors for the plant and degrees of accumulations for the elements need to know phytoextraction of the heavy metal elements within the soils.
