These principles were later known in the Renaissance of Europe as the law of superposition of strata, the concept of catastrophisim, and the doctrine of uniformitarianism. He covered subjects like wind energy , hydrodynamic power , melting cookers, transport of ores , extraction of soda , sulfur and alum , and administrative issues.

The book was published in Nicolas Steno is credited with the law of superposition , the principle of original horizontality , and the principle of lateral continuity : three defining principles of stratigraphy. Previous attempts at such statements meet accusations of heresy from the Church. They were independently anticipated by William Smith's stratigraphic studies on England and Scotland.

Sir Charles Lyell first published his famous book, Principles of Geology , in and continued to publish new revisions until he died in He successfully promoted the doctrine of uniformitarianism. Many of these involve the ability to provide the relative ages of strata or the manner in which they were formed. The principle of intrusive relationships concerns crosscutting intrusions. There are a number of different types of intrusions, including stocks, laccoliths , batholiths , sills and dikes.

The principle of cross-cutting relationships pertains to the formation of faults and the age of the sequences through which they cut. Faults are younger than the rocks they cut; accordingly, if a fault is found that penetrates some formations but not those on top of it, then the formations that were cut are older than the fault, and the ones that are not cut must be younger than the fault. Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

The principle of inclusions and components states that, with sedimentary rocks, if inclusions or clasts are found in a formation, then the inclusions must be older than the formation that contains them. For example, in sedimentary rocks, it is common for gravel from an older formation to be ripped up and included in a newer layer. These foreign bodies are picked up as magma or lava flows, and are incorporated, later to cool in the matrix. As a result, xenoliths are older than the rock which contains them.

The principle of original horizontality states that the deposition of sediments occurs as essentially horizontal beds. This principle allows sedimentary layers to be viewed as a form of vertical time line, a partial or complete record of the time elapsed from deposition of the lowest layer to deposition of the highest bed.

As organisms exist at the same time period throughout the world, their presence or sometimes absence may be used to provide a relative age of the formations in which they are found. The principle becomes quite complex, however, given the uncertainties of fossilization, the localization of fossil types due to lateral changes in habitat facies change in sedimentary strata , and that not all fossils may be found globally at the same time.

Issue Volume 3 No. DOI Letak kedekatan lokasi geografis dengan lempeng tektonik Eurasian dan Indo-Australian membawa konsekuensi logis terhadap tingginya resiko kebencanaan, terutama gempa dan tsunami, bagi Indonesia. Kota Mataram yang merupakan ibukota Provinsi Nusa Tenggara Barat merupakan salah satu wilayah yang perlu mendapatkan perhatian khusus terhadap resiko bencana tsunami. Sebagai langkah awal, identifikasi lokasi yang paling rentan terhadap resiko bencana tsunami perlu dilakukan dengan memadukan aspek-aspek fisik, sosial dan ekonomi. Penelitian ini bertujuan mengidentifikasikan lokasi paling rentan terhadap resiko bencana tsunami di Kota Mataram dengan menggunakan analisa sistem informasi geografis GIS. Hasil analisis berhasil menemukenali bahwa Kota Tua Ampenan merupakan wilayah di Kota Mataram dengan nilai indeks gabungan tertinggi yang mencerminkan tingkat kerentanan yang paling tinggi.

Pleistocene reefs in eastern part of Indonesia are abundantly found along the coast as raised reef. Therefore the reef size is narrow. The objective of this research is to define depositional environment based on coral development. Several methods were applied such as intersect lines which were perpendicular to the cliff, geochemical and petrographic analyses, as well as paleoenvironment interpretation. Based on facies association and organism accumulation, the depositional environment of Pleistocene reef is interpreted to be developed in a small reef complex on an unstable basement. The reef has experienced at least 3 three times of sea level fluctuation. Bromfield, K.

Pulau Sulawesi terletak pada zona pertemuan diantara tiga pergerakan lempeng besar yaitu pergerakan lempeng Hindia-Australia dari selatan, lempeng Pasifik dari arah timur dan lempeng Asia bergerak relative pasif ke tenggara. Data pengamatan stasiun CORS bisa digunakan untuk mempelajari aktivitas tektonik dan karakteristik fenomena alam dan deformasi yang terjadi di suatu daerah. Penelitian ini menghasilkan arah pergeseran dari masing-masing stasiun CORS dan kecepatan pergeseran. Sulawesi Island is located in the zone of meeting between three large plate movement is the movement of the Indian-Australian plate from the south, the Pacific plate from the east and Asian plate moves relatively passive to the southeast. CORS station observation data can be used to study the tectonic activity and characteristics of natural phenomena and deformations that occur in an area. Therefore conducted this research on the velocity rate CORS station on the island of Sulawesi to know the value and the vector direction of the shift position CORS point. This research resulted in a shift direction of each station CORS and speed the shift.
