The highest shear strength Carbonaceous shale thesis malaysia identified at cm layer with Shearing was continued until the maximum stress or peak point has been clearly defined, that is until at least four consecutive readings indicate a decrease or equal in load.
Shear strength at cm depth gave the highest value when treated with NGF treatment. Appropriate soil amendments and suitable vegetation plant mix species to be grown on this cut slopes become vital and needs immediate action.
Therefore, the combined effect of root reinforcement and liming could account for the observed overall improvement of shear strength of the shale.
Shear strength of a soil mass is the internal resistance per unit area that the soil mass can offer to resist failure and sliding along any plane inside it 5. Associated with shear veins are several types of extensional veins including sub-vertical extensional vein arrays, hydrothermal quartz breccias and stockwork in felsite rocks.
Figure 4 indicated that the effect of soil treatments on root density where with NGF treatment gave the highest root density as compared to the others treatment. The normal load needs to reflect the applied vertical load plus the weight of the load block and top half of shear box.
Foliar fertilizer provides additional macro and micro-nutrients for plants establishment. The cohesion value in every layer in NGF treatment relatively was slightly lower compared to the other treatments.
The peak strength or shear strength was plotted for each layer of carbonaceous shale that was treated with various soil treatments. Overall, both in the Central Gold Belt and the Northwest Domain in Langkawi Islands, gold content in sedimentary pyrite correlates strongly with V, U, and Se suggesting a strong control of organic processes on Au introduction into sedimentary pyrite.
The good correlation of V with Au, Zn, Cd, and Sb in diagenetic pyrite suggests that these trace elements were all concentrated by organic processes. These adverse chemical conditions of the substrate imply that the potential for spontaneous re-vegetation is low as evidenced by shale cut slopes, which remain un-vegetated several years after exposure.
The cutter ensured that the size of each sample can be uniformly controlled for a good fit into the shear box. The highest gold contents which vary from 0. The rapid growth of Brachiaria ruziziensis, Colopogonium mucunoides and fast root distribution through the carbonaceous shale play an important role in controlling erosion through binding soil particles physically into stable aggregates.
The box was grown with mixed plants species Brachiaria ruziziensis and Colopogonium mucunoides. This line is the failure envelope or the Coulomb envelope. Partial variation in each sample is related to the in situ decay of U and Th but the remainder relates to initial isotopic differences during crystallization of pyrite.
The presence of vegetation roots would result in an overall increase in the soil strength.
In the NPK fertilizer treatment, a similar trend could be observed where higher shear strength was obtained compared to the control in each layer. In addition to that, the depth of cm, the shear strength was slightly lower as compared to NGF.Belt, Peninsular Malaysia Charles Makoundi MSc A research thesis submitted in partial fulfillment of the requirements for the degree of Master of Science School of Earth Sciences, CODES Centre of Excellence in Ore carbonaceous shale.

‘The distinguishing feature of the lowermost sequence is the presence of coal or carbonaceous shale within alluvial and lacustrine strata.’. Shale is one of the mm.
This combined with yearlong high temperatures common rock types in Malaysia. Many of them are causing intense chemical weathering and formation of carbonaceous in nature. Some of the shale slopes could thick residual soil profiles which in certain locations can be observed along the main highways in Malaysia.
