Abstract

As a Muslim, the guidance used in worship comes from the Quran and Hadiths. One of the authentic Hadiths by Muslim states that Arabia will turn green again. This research aims to explain the greening of Arabia in the past and future perspectives from a geological and meteorological point of view. The method used in this study is a review study, combining the theory of plate tectonics on the Arabian Plate and the meteorological cycles that will occur in the future using the theory of natural radiative forcing in climate change. Discoveries of mollusks and fossils that lived in water in hot deserts provide evidence of past wet conditions before it turned hot again. There have been 18 warm climate cycles and 17 climate cycles since 5.3 million years ago. The results of this research indicate that Arabia will turn green again, both from a geological and meteorological approach. The geological approach estimates that Arabia will turn green again in approximately ~25 million years, while the meteorological approach suggests at least 13,000 years in the future when the Earth reaches its opposite precession peak. The influence of meteorological cycle periods is shorter compared to the long-term effects of plate movements. The possibility of Arabia turning green in the future is indeed true, in line with the statements of the Prophet's Hadith.

Abstract

Sulawesi is a tectonically active area with convergent triple-junction amidst Eurasian, Indo-Australian and Pacific Plate. The study area is located in the suture zone of sedimentary Banggai-Sula Microcontinent and East Sulawesi Ophiolite. This research is aimed to determine fault activity and rate of tectonic uplift of Luwuk mountainous area. Field geological mapping had been done to determine lithology and geological structure along with morphometric analysis to measure definitive result of tectonic activities. Geological structure features which encountered in this area are Batui Thrust, Pasini Thrust, Lobu Balongan Fault Zone, and Lambangan Anticline. The sedimentary rocks have average N315oE dip direction with angle of 41o. Based on tectonic geomorphology and morphometric analyses are resulting the most active tectonic areas passed by the Batui and Pasini Thrust which have NE-SW direction and Lobu Balolang Fault Zone relative to others. The Batui Thrust is considered as active fault intersected the East Sulawesi Ophiolite and Banggai-Sula Microcontinent which segmented with wrench faults. Number of thrust faults parallel to the Batui Thrust generate Batui Thrust Belt which propagate from the ultramafic rocks to the sedimentary rocks within the suture zone. As a result, the presence of active fault is uplifting the East Arm of Sulawesi with 0.408 ± 0.008 mm and 0.213 ± 0.046 mm uplift rate per year by the presence of high altitude Celebes Molasses. These rates are getting higher to the west. Keywords: Batui Thrust, East Sulawesi Ophiolite, Luwuk, morphometry, tectonic geomorphology, uplift rate
