Lake Sfânta Ana
Lake Sfânta Ana (; ; ) is the only crater lake in Romania located in the volcanic crater of the Ciomad volcano of the Eastern Carpathians, near Tușnad in the Natural Reserve of Mohoș, Harghita County, Romania Romania is a country located at the crossroads of Central Europe, Central, Eastern Europe, Eastern and Southeast Europe. It borders Ukraine to the north and east, Hungary to the west, Serbia to the southwest, Bulgaria to the south, Moldova to .... Palynology studies concluded that the history of Lake Saint Anne began about 9,800-8,800 years ago, at the stage of peat bog and shallow lake. The depth of Saint Anne Lake is constantly decreasing. In 1867 it was 12 m, but now it is less than 7 m. In 2005, the maximum depth of the lake was 6.4 m and the sediment thickness was about 4 m. The lake is supplied exclusively from precipitation, therefore the degree of mineralization of the water is very low. The water purity approaches that of distilled water, with only 0. ...

Volcanic Crater Lake
A volcanic crater lake is a lake in a volcanic crater, crater that was formed by explosive eruption, explosive activity or a caldera, collapse during a types of volcanic eruptions, volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the Rim (craters), crater rim, is filled by water. The water may come from Precipitation (meteorology), precipitation, groundwater circulation (often Hot Spring, hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoes, and these are commonly refe ...

Ciomad
Ciomadul () is a dormant volcano in Romania. It is in the Eastern Carpathians, between the spa towns of Băile Tușnad and Balvanyos. Ciomadul lies at the southeastern end of the Carpathian volcanic chain and it is the youngest volcano of the Carpatho-Pannonian region. Ciomadul consists of several lava domes with two embedded explosion craters known as Mohoș and Sfânta Ana, the latter of which contains a crater lake, Lake Sfânta Ana. The dominant volcanic rock at Ciomadul is potassium-rich dacite. Volcanic activity at Ciomadul commenced with effusive activity about one million years ago. Most of the volcano was constructed between 650,000 – 500,000 years ago. Between 56,000 and 32,000 years ago explosive volcanic activity occurred at Ciomadul. Both the exact dates of the various eruptions and of the formation of the Sfânta Ana and Mohoș craters are unclear, partly because dates obtained by potassium-argon dating and other dating techniques deviate from each other.

Eastern Carpathians
Divisions of the Carpathians are a categorization of the Carpathian mountains system. Below is a detailed overview of the major subdivisions and ranges of the Carpathian Mountains. The Carpathians are a "subsystem" of a bigger Alps-Himalaya System that stretches from western Europe all the way to southern Asia, and are further divided into "Geologic province, provinces" and "subprovinces". The last level of the division, i.e. the actual mountain ranges and basins, is usually classified as "units". The main divisions are shown in the map on the right. To generalize, there are three major provinces (regions): Western Carpathians, Eastern Carpathians, and the Southern Carpathians. Naming conventions The division is largely (with many exceptions) undisputed at the lowest level (except for the Ukraine, Ukrainian part), but various divisions are given for the higher levels, especially for the penultimate level. A geomorphology, geomorphological division has been used as much as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palynology
Palynology is the study of microorganisms and microscopic fragments of mega-organisms that are composed of acid-resistant organic material and occur in sediments, sedimentary rocks, and even some metasedimentary rocks. Palynomorphs are the microscopic, acid-resistant organic remains and debris produced by a wide variety of plants, animals, and Protista that have existed since the late Proterozoic.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds., 2005, ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimentary rocks and sediments. Palynology does not include diatoms, foraminiferans or other organisms with siliceous or calcareous tests. The name of the science and o ...

Saint Anne
According to apocrypha, as well as Christianity, Christian and Islamic tradition, Saint Anne was the mother of Mary, mother of Jesus, Mary, the wife of Joachim and the maternal grandmother of Jesus. Mary's mother is not named in the Bible's Gospel#Canonical gospels, canonical gospels. In writing, Anne's name and that of her husband Joachim come only from New Testament apocrypha, of which the Gospel of James (written perhaps around 150 AD) seems to be the earliest that mentions them. The mother of Mary is mentioned but not named in the Quran. Christian tradition The story is similar to that of Samuel, whose mother Hannah (biblical figure), Hannah ( ''Ḥannāh'' "favour, grace"; etymologically the same name as Anne) had also been childless. The Immaculate Conception was eventually made dogma by the Catholic Church following an increased devotion to Anne in the twelfth century. Dedications to Anne in Eastern Christianity occur as early as the sixth century. In the Eastern Orthodox ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landforms Of Székely Land
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Geography Of Harghita County
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
