感星의 地質循環은 感星의 表面과 內部에 作用하는 여러가지 內外因的인 에너지의 效果를 나타내므로 地質循環을 仔細히 考察하면 感星들의 地質作用 歷史및 現發達단계에 關한 事實들을 推測할 수 있게 된다. 地球는 기원암이 침식되어 재순환하는 閉鎖環(closed-loop)의 地質循環인데 比해 달은 結晶質原始地殼이 逆行될 수 없는 開放環(open-loop)의 地質循環을 보인다. 그리고 火星의 地質循環은 "원시적"이고 地質作用이 정체한 달과 원숙하고 地質作用이 활동적인 地球와의 중간단계의 發達을 보여준다. 예비적인 "地質循環圖"는 火星 이 원시적인 噴火地域과 변형된 완만한 地域으로 분할되었음을 보여준다. 火星은 分明히 地球와 같은 構造的 活動(tectonic activity)의 단계에 돌입하고 있다.

Sangdong tungsten-molybdenum skarn orebodies embedded in the Cambrian limestones of the Myobong Slate and the overlying Pungchon Limestone. Orebodies show a generalized zonal distribution of the major component minerals: a central quartz-mica zone is surrounded by an amphibole-rich zone, which in turn is enveloped by a pyroxene-garnet zone. Scheelite is highly concentrated in the quartz-mica zone. Some charicteristic features are recognized in Sangdong granite: 1. Sangdong granite shows more than two phases of evolution and strongly potassic-alteration. 2. The ratio of Fe_2O_3/FeO and K_2O/Na_2O is increased towards central part of granite (86-3 granite core). 3. Central part of granite, having high Rubidium content, was more differentiated than marginal part. 4. Sangdong granite, belong to Tungsten-Molybdenium metallogenic province has higher W and Mo average content than those of Imog and Geodo granitic rocks which belong to Lead-Zinc and Copper metallogenic provinces, respectively. These facts suggest that the central part of Sangdong granite roled mainly W and Mo mineralization of the Sangdong mine. Similar geochemical charicteristics between chemical elements of granite and skarn minerals indicate that the Sangdong granite is deeply connected with mineralization of skarn orebodies.

Physical properties in 21 representative sandstones of the Gyeongsang Supergroup have been studied in the laboratory,. For the purpose of this study, density, porosity, saturation moisture content, compressional wave(P-wave) and shear wave(S-wave) velocity were measured. Elastic moduli was calculated by P-wave and S-wave velocity. The ratio of P-wave to S-wave and the effect of water saturation on velocity were evaluated. The results of this study are summarized as follows. : Sandstones of the Gyeongsang Super-group range in density from 2.45 to 2.68 g/㎤, in porosity from 0.55 to 5.47%,in saturation moisture content 0.20 to 2.25%. In grain size,density is higher in coarse grained than in fine grained, and porosity and saturation moisture content is higher in fine grained than in coarse grained. Elastic wave velocity varies in P-wave from 3,050 to 4,450m/sec, in S-wave from 1,650 to 2,870 m/sec.Also wave velocity is higher in coarse grained than in fine grained sandstones. V_p/V_s is between 1.41 and 1.85, the value less than 2.0 is characteristic of well consolidated sandstones. Use of V_p/V_s has the additional advantage of density information. It is observed that water saturation increases the P-wave velocity considerably, in some cases as high as 30% if compared with dry state. The range of Poisson's ratio varies from 0.05 to 0.29 and Young's modulus 1.77×10 exp (5) ㎏/㎠ to 5.17×10 exp (5) ㎏/㎠. Rigidity modulus range from 0.69×10 exp (5) ㎏/㎠ to 2.27×10 exp (5) ㎏/㎝. The elastic moduli increases as the P-wave velocity increases but Poisson's ratio is an exception. Physical properties of sandstones of Gyeongsang Supergroup seem to be caused by depositional environments, but not caused by time (stratigraphy) and space (geography).

The Cretaceous sandstone and felsite distributed in north western border part of Daegu city are studied in viewpoint of engineering geology with an emphasis of development of joints. The probability of continuity of sandstone is 0.69 and that of felsite is 0.56. The rate of discontinuity of sandstone is 0.48 and that of felsite is 0.60. These values reflect that the rocks have been strongly jointed. k_o value of the sandstone is close to its k_a value and it is suggested for the sandstone have been in active state. On the other hand, k_o value of the felsite is close to its K_p value and it is also suggested for the felsite have been in passive state. Therefore in order to maintain the stability of these rocks. δ value should be changed to be less than 13.2, thus, the rocks are able to maintain its stability.

태양계 혹성의 대부분은 위성을 가지고 있다. 지구는 하나의 큰 위성(달)을 가지고 있어 이런 체계를 double planet라고 한다. 천제 가운데 오직 지구와 달만을 사람이 직접 탐사할 수 있었다. 이를 통하여 달에 대한 기존 가설들이 하나, 둘 수정 보충되어졌었으며 태양계와 우주에 관한 지식에 큰 진보가 이루어지고 있다. 여기에서는 달의 지질에 관하여 지구의 지질과 비교하여 살펴보기로 한다. 달과 지구는 매우 유사하다. 달은 지구와 같이 성권구조를 이루고 있으며, 46억년이라는 같은 연령치를 보이고 내부는 고열로써 온도는 심도에 따라 증가하며, 암석은 비율에 따라 다르지만 지구와 같은 화학원소로 구성되어 있으며 과거에는 화산활동이 있었다.

The stratigraphic interval (the lower part of the Hayang Group) between the lower boundaries of the Chilgok and the Banyawol Formations is subdivided into 11 lithozones: namely, (1) pebble bearing reddish zone, (2) dark-grayish zone, (3) tuffaceous reddish zone, (4) variegated-conglomerate bearing zone (5) reddish zone (6) alternation zone. (7) dark-grayish zone (8) alternation zone. (9) pyroclastic-breccia-bearing zone. (10) alternation zone, and (11) reddish zone. Zones (1) to (3) are correlated with the lower part of the Chilgok Formation: zone (10) and (11) are correlated with the upper part of the Haman Formation: and zones (4) to (9) are correlated with the Hakbong Member, Sinla Conglomerate, and the middle and the upper parts of the Chilgok Formation together. The radical lateral lithologic change of the lower part of the Hayang Group between the northern and the southern sides of the Palgongsan line is interpreted to have been caused by differential sedimentation due to the Palgongsan synsedimentational fault The Hamaji member of the Banyawol Formation and Sinryong conglomerate (good key bed of the boundary between the Haman and the Banyawol Formations) are newly described
