  • Transmission electron microscopic study including single particle electron diffraction and morphological observation using replica and thin section was carried out for the Sancheong halloysite. Halloysite tube generally consists of inner circular and outer polygonal leaves. Primary triangular or concave voids are found between inner and outer leaves. Crosssection of halloysite tubes whose diameters are smaller than 500${\AA}$ are generally circular, whereas those larger than 500${\AA}$ are polygonal. Electron diffraction pattern of thick polygonal halloysite tube shows that it has a 2-layer monoclinic structure as suggested by previous workers.

  • Low-field anisotropy of magnetic susceptibility (AMS) was measured with 247 samples from 17 sites of Pre-Cambrian anorthositic rocks in the Hadong-Sanchong area, southwestern part of the Ryongnam Block. Tectonic stress-direction is defined by the minimum susceptibility (k3) direction, and flow-direction by the maximum susceptibility (k1) direction. Five sites rendered self-consistent NW-SE site-mean tectonic stress-direction. Even though a general fold test for every site was not possible due to the homoclinal nature of the bedding attitudes, a site with various bedding attitudes shows far better clustering of the k3-direction before the bedding-tilt correction. The in-situ NW-SE tectonic stress-direction is consistent over the study area and compatible with petrographic foliation observed in metamorphic rocks in and arround the study area, suggesting a regional compressive force acted after the emplacement of the anorthositic rocks. On the other hand, flow-directions obtained from six sites varies from site to site. Strong-field IRM experiments show predominance of titanomagnetites over a small amount of hematite in some samples.

  • This study was conducted to investigate the effects of application of composted cattle manure (CCM) on the productivity of the whole crop rice (WCR) and Italian ryegrass (IRG) on both Sancheong and Asan area from 2005 to 2008. Application levels of CCM such as chemical fertilizer (CF), CCM 150% and CCM 200% were tested in paddy field. Amount of CCM was adjusted equal to total nitrogen value relative to its value of CF. Mean dry matter yield (DMY) of WCR and IRG increased in order; CCM 200% > CF > CCM 150% in Asan and there was no significant difference between CCM 200% and CF. In Sancheong, DMYs of WCR and IRG significantly decreased (p<0.05) in order CF > CCM 200% > CCM 150%. The plant length and number of tiller of WCR were not different among treatments, however the percentage of ripeness of WCR was higher (p<0.05) in CF compared to CCM 150% and CCM 200%. Also, there were no differences in NDF and ADF contents, however CP content was higher (p<0.05) in CF treatment compared to CCM 150% and CCM 200%. Based on the results of this experiment, IRG-WCR double cropping system with application of CCM may be effective in producing the forage resources of 18~20 tons every year with eco-friendly way.

  • This study was carried out to examine the effect of soil amendment treatments [(organic fertilizer: 20 kg $tree^{-1}$; compound fertilizer+wood-char fertilizer: compound fertilizer 4 kg $tree^{-1}$+wood-char 2 kg $tree^{-1}$; lime fertilizer: 3 kg $tree^{-1}$; mixed fertilizer: compound fertilizer 1 kg $tree^{-1}$+organic fertilizer 10 kg $tree^{-1}$+wood-char 1 kg $tree^{-1}$; control (no fertilizer)] on flowering and fruit characteristics in chestnut (Castanea crenata S. et Z.) orchards in Jinju and Sancheong, Gyeongsangnam-do. Diameter of fruiting shoot increased generally after soil amendment treatments compared with the control, while number of leaf, female and male flowers were not affected by the treatments. Nut weight increased after soil amendment treatments in Jinju, but was not affected by the treatments in Sancheong. There was a positive correlation between soil pH (r=0.91) or exchangeable $Ca^{2+}$ (r=0.99) and nut weight in Jinju and a positive correlation (r=0.97) between organic carbon content and soluble solid concentration, while a negative correlation (r=-0.92) between exchangeable $Mg^{2+}$ and soluble solid concentration of nuts in Jinju. However, the nut weight and soluble solid concentration in Sancheong were not correlated with soil properties. The results indicate that the characteristics of flowering and nuts in chestnut orchards depend on soil properties after soil amendment treatments between regions which show better responses on poor sites than on good sites.

  • This study aimed to investigate orographic precipitation and green dam (water conservation function) characteristics in a deciduous forest watershed in the region of Mt. Ungseok, Sancheong, Gyeongnam, South Korea. The rainfall and runoff of the watershed were monitored for six years (2011~2016) at the weather station and at the weir of the watershed, respectively. During the study period, the rainfall in the watershed (mountainous area) was larger than that of the meteorological station (flat area) nearest to the watershed. Besides, compared to the normal year (1981~2010), the rainfall has increased and the seasonal distribution of rainfall of the mountainous area has changed. These changes might have been caused by climate change. The runoff ratio was highest in spring, followed by winter, summer and fall, whilst the runoff was highest in summer, followed by spring, fall and winter. This difference seems to be due to the melting of snow in dry spring and intensive rainfall in summer. The total runoff in the watershed was calculated as $10,143.8ton{\cdot}ha{\cdot}yr^{-1}$.

  • Ilmenite ore bodies are deposited within the Precambrian anorthosite body distributed in the Hadonggun and Sancheonggun district, Gyeongsangnamdo. This study tries to identify the occurrence of ilmenite ore body in titanium mine area distributed in Wheolheongri, Okjongmyon, Hadonggun and six mining concession areas (Danseong claim no. 64, 65, 74, 75, 84, 85) in Danseongmyon, Sancheonggun. Wheolheongri ilmenite ore body occurs as vein with about 10~50 m width and 100 m length and shows NNE strike and NW dipping. High grade ore with $TiO_2$ 20 wt% in this area is distributed in intercumulated anorthosite and is sheared and brecciated. Ilmenite occurring in this type is commonly associated with hornbelnde. Ilmenite ore bodies distributed in Danseonggun, Sancheongmyon are deposited in layered anorthosite. They occur as stratiform with variable width from several and several tens meters. Ilmenite which is disseminated in the matrix is sheared and elongated. This type shows generally low grade ($TiO_2$ 1.0~6.0 wt%). The ilmenite ore bodies occur as vein and stratiform, and the former shows higher grade than the latter.
