Fukiishi
( or "roofing stone") were a means of covering burial chambers and Tumulus, burial mounds during the kofun period of Japan (). Stones collected from riverbeds were affixed to the slopes of raised kofun and other burial chambers. They are considered to have descended from forms used in Yayoi period, Yayoi-period tumuli. They are common in the early and mid-Kofun periods, but most late Kofun-period tumuli do not have them. Origin and ancestry Tombs covered with fukiishi appear sporadically in Western Japan from the mid-Yayoi period and continue into the Kofun period. Fukiishi are thought to be one element of the characteristics of the period of kofun at the time that they were making their first appearance; what are thought of as the oldest examples of what was to lead the generally fixed form are seen at Hashihaka Kofun and the presumed slightly older Hokenoyama Kofun in the city of Sakurai, Nara, Sakurai in Nara Prefecture. Neither fukiishi nor haniwa accompany mounds fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kofun
are megalithic tombs or tumulus, tumuli in Northeast Asia. ''Kofun'' were mainly constructed in the Japanese archipelago between the middle of the 3rd century to the early 7th century AD.岡田裕之「前方後円墳」『日本古代史大辞典』大和書房、2006年。 The term is the origin of the name of the Kofun period, which indicates the middle 3rd century to early–middle 6th century. Many ''kofun'' have distinctive keyhole-shaped mounds (). The Mozu kofungun, Mozu-Furuichi kofungun, Furuichi kofungun or tumulus clusters were inscribed on the World Heritage Sites in Japan, UNESCO World Heritage List in 2019, while Ishibutai Kofun is one of a number in Asuka-Fujiwara residing on the World Heritage Sites in Japan#Tentative List, Tentative List. Overview The ''kofun tumuli'' have assumed various shapes throughout history. The most common type of ''kofun'' is known as a , which is shaped like a keyhole, having one square end and one circular end, when viewed from a ...

Soil Mechanics
Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic matter, organic solids and other matter.Mitchell, J.K., and Soga, K. (2005) Fundamentals of soil behavior, Third edition, John Wiley and Sons, Inc., .Powrie, W., Spon Press, 2004, ''Soil Mechanics – 2nd ed'' A Guide to Soil Mechanics, Bolton, Malcolm, Macmillan Press, 1979. Along with rock mechanics, soil mechanics provides the theoretical basis for analysis in geotechnical engineering, a subdiscipline of civil engineering, and engineering geology, a subdiscipline of geology. Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that ar ...

Paleoecology
Paleoecology (also spelled palaeoecology) is the study of interactions between organisms and/or interactions between organisms and their environments across geologic timescales. As a discipline, paleoecology interacts with, depends on and informs a variety of fields including paleontology, ecology, climatology and biology. Paleoecology emerged from the field of paleontology in the 1950s, though paleontologists have conducted paleoecological studies since the creation of paleontology in the 1700s and 1800s. Combining the investigative approach of searching for fossils with the theoretical approach of Charles Darwin and Alexander von Humboldt, paleoecology began as paleontologists began examining both the ancient organisms they discovered and the reconstructed environments in which they lived. Visual depictions of past marine and terrestrial communities have been considered an early form of paleoecology. The term "paleo-ecology" was coined by Frederic Clements in 1916. Overview of ...

Petrology
Petrology () is the branch of geology that studies rocks, their mineralogy, composition, texture, structure and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because both make heavy use of chemistry, chemical methods, and phase diagrams. Sedimentary petrology is commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock. Modern sedimentary petrology is making increasing use of chemistry. Background Lithology was once approximately synonymous with petrography, but in current usage, lithology focuses on macroscopic hand-sample or outcrop-scale description of rocks while petrography is the speciality that deals with microscopic details. In the petroleum industry, lithology, or more specifically mud logging, is the graphic representation of geological formations being drilled through and drawn ...

The five provinces were called ''go-kinai'' after 1760.Nussbaum, "''Gokishichidō''" in . The name is still used to describe part of the Kansai region, but the area of the Kinai corresponds only generally to the land of the old provinces.
