Jindong Granites are plotted mainly in the region of granodiorite~diorite of the Streckeisen's diagram, while Yucheon-Eonyang Granites and Onjonri Granites in the region of monzo-granite and monzo-granite~granodiorite, respectively. Jindong Granites show a differenciation trend of calc-alkaline magma, and its magmatic evolution from intermediate to acidic rocks, which might form mineralizing solution, is consistant with the general path of the Cretaceous granitic rocks including Yucheon-Eonyang Granites and Onjongri Granites. The differenciation index (D.I.) is 35~80 for Jindong Granites, which is lower than 85~95 of Yucheon-Eonyang Granites and is partly overlapped by 67~84 of Onjongri Granites. There is clear difference in content of some major and trace elements between Jindong Granites of Cu province and the other granitic rocks of Pb-Zn and Mo provinces. Between these metallogenic provicnes, Cu content is high in Jindong Granites near Haman-Gunbuk mineralized zone, while Pb and Zn are relatively abundant in Yucheon-Eonyang Granites and Mo in Onjongri Granites. Therefore, Jindong Granites of the Cu province are distinguishable by chemical compositions and their related geochemical characteristics from the other Cretaceous granitic rocks of Pb-Zn and Mo provinces. However, the content of Cu and Cl in biotite is applicable to distinguish a productive phase from a barren phase of Jindong Granites, because Cu and Cl show a trend to be concentrated in biotite of Jindong Gratites in the Haman-Gunbuk mineralized zone.

In the Donguebogam it is written that nephrite well waters, which are derived from the mountain where nephrite is produced, has wide medical effects to let man keep healthy body, black hair and long live. However, nephrite itself ha limited medical effects to cure stomach fever, tightness in the chest, asthma and thirstiness. This investigate is to study mineralogically, geochemically and oriental medically how it is possible that the nephrite well waters have wider medical effects in comparison to nephrite with limited medical effects. Nephrite consists of tremolite Ca_(2)Mg_(5)Si_(8)O_(22)(OH)_(2), which is called actinolite Ca_(2)(Mg,Fe)_(5)Si_(8)O_(22)(OH)_(2) when its Mg is partly replaced by Fe (<10%). The tremolite is generally associated with talc, calcite and chlorite in the ore deposit formed by the hydrothermal solutions from granitic intrusives in the dolomite and dolomitic limestone areas in Korea. These five minerals of nephrite, actinolite, talc, calcite and chlorite are all recorded in the Dongurebogam (Heo Jun, 1613) and Bonchogangmog (Lee Si Jin, 1578) as medical minerals to cure various diseases. Therefore, waters derived from nephrite deposits may contain chemical compositions related to not only nephrite but also the other medical minerals and have wider medical effects than nephrite itself.
