바위는 겉과 속의 색깔이 다르다. 바위의 겉은 광물의 풍화로 색깔이 변하므로 그 속색깔을 알아보려면 망치로 풍화된 겉을 떼어내야 한다. 그래서 지질학자들은 이를 '백견이 불여일타'라고 한다. 그런데 요즘 지질학계에는 야외 지질조사를 기피하고 실내에서 시료를 분석하는 경향이 만연되고 있어 안타깝다. 지질학의 진리를 캐러 야외로 나가자.

Micropaleontological analyses of the bathic foraminifera of 132 subtidal surface samples of Asan Bay located in the middle of the western coast of Korea, fringing the Yellow Sea collected during late May-early June 1982, shows the results as follows; -Forainiferal numbers of total assemblages are influenced by hydrodynamic and ecologic factors as well as by the sedimentation in the study area. -Badly preserved faunas including replaced faunas seemed to be fossils, all having living counterparts in the study area and showing a somewhat similar type of wall structures with those of the total assemblages and showing no characteristic bathymetric occurrence compared to that of the biocoenose s.1. of the species, lead to infer theirprobable derivation from the environment without a remarkable environmental difference from the study area. But this inference demands further study in consideration of the physical conditions of the study area. -Living/total ratios show a strong negative correlation with the total foraminiferal numbers excluding replaced faunas. But this trend is somewhat deviated in the relatively high ratios. -Fisher-alpha diversity indices of the total assemblages excluding replaced faunas are lying between 1.7 and 3.7. Totals assemblages are mainly composed of hyaline forms with limited porcelaneous and agglutinated ones.

The most usually adopted methods from the collection of samples laboratory procedures, to basic analysis of assemblages for the quantitative study of benthic foraminifera are reviewed. Standard methods of treatment of sampleswith emphasis on the effective detection of contamination through routine dip of sieved into Methylene Blue solution after every washing of samples are proposed to minimize differences due to individuals and for comparisons of results in future. Some basic characteristics for the quantitative analyses are also reviewed with appropriate examples. These characteristics are related to toraminiferal abundance, wall structures, condition of test conservation, diversity and related characteristics, faunal similarith between samples, and occurrence of planktonic foraminifera.

A 2.3 m-long core obtained from Marian Cove, King George Island in the South Shetland Islands, West Antarctica shows clues to the glaciomarine sedimentation during the Holocene. The lower part below 115cm-deep of the core is predominated by coarser material such as diamictons compared with the higher part above 105cm dominated by finer material (rhythmite and massive muds). Based on the granulometric features the coarse materials are generally supposed to be glacially-driven and basal tills, whereas the fine materials appear to originate from various sources such as meltwater-supplied, glacially-supplied, wind-blown, and organic origins. However, the presence of erratic coarse particles in the finer materials suggests the ice-rafted origin of the relevant materials. The lower part below 105cm-deep of the core was characterized by lower TN, TC, and TOC contents, and by higher TS and CaCO$_3$ contents compared with its upper part. No significant changes in C/N ratio were shown throughout the core. The ice cliff along the east side of Marian Cove seemed to locate to the west by 1.6km at 8,300 years B. P. on the basis of the repetitive occurrence of rhythmite and diamicton. Since the retreat of ice cliff in 7,970${\pm}$70 years B. P. the sediments of Marian Cove were dominated by fine materials and ice-rafted materials. The abrupt increase of coarse materials in 175cm-4 deep seems to result from supply of coarse materials due to earthquake or other drastic phenomena.

영국의 해부학자 리차드 오웬이 1841년 공룡을 '무서운 도마뱀'으로 이름지으면서 공룡은 찬피 동물이라고 생각해 왔다. 그 후 공룡을 연구한 많은 학자들이 '찬피 동물이냐, 아니냐'를 싸고 주장을 달리해 왔다. 풀리지 않은 수수께끼 공룡의 세계를 들여다 본다.

우리는 인류의 역사를 화석을 통해 추정한다. 사람의 먼 조상은 4백만년 전에 나타났고 이집트에서는 5천년 전 뇌수술을 한 흔적이 당시의 두개골에 나타나 있으며 남아메리카 원주민들도 흑요석 칼로 뇌수술했다.

한국지구과학회 1999년도 추계 학술발표에서 발표된 한글 요약문에 대한 의견
장순근,Chang, Soon-Keun 한국지구과학회 2000 한국지구과학회지 Vol.21 No.4
The abstracts written in Korean presented at the Fall Meeting of the Korean Earth Science Society held at the Kangwon National University in October, 1999 were reviewed. They are dotted with foreign expressions and obscure wordings as well as difficult expressions and very long sentences. The foreign expressions are those originated from Japanese, English, and Chinese expressions and words. Several suggestions are made to increase the ability to write good abstracts and articles in Korean on the earth sciences. They include reading many books on natural sciences for general readers, writing sentences not exceeding 20 words, critical reading by professor or colleagues, and open mind to accept their criticisms. The authors should pay attention not to commit various errors shown in Table 2 in this paper.
