The exposure of Mesozoic rocks in the Mangilu area, both as a result tectonic deformation form mélange, low-high degree metamorphism and deep-sea sediments (flysch, radiolarian cherts, sediment flow olistostrome), which formed subduction zone indicates complex accretionary rocks. purpose this study is to identify trace era. method used was field observation, including collection geological data...

argillite, interbedded basalt and abundant diabase sills. More specifically, the rhodonite is located above a section of grey, black and pale green chert and argillite at the base of the unit [IIPPvs( I ) on Figure 2-15-21 and about 50 metres below an upper section of brightly coloured, maroon, red, green and grey chert and argillite [Unit IIPPvs(2) on Figure 2-15-21, This stratigraphic positio...

Since each rock type represents different deformation characteristics, prediction of the damage beforehand is one most fundamental problems industrial activities and engineering studies. Previous studies have predicted stress–strain behaviors preceding failure; however, quantitative analyses progressive in rocks under stress not been accurately presented. This study aims to quantify pre-failure...
