A lahar is a type of mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris, and water. The material flows down from a volcano, typically along a river valley. Lahars are extremely destructive: they can flow tens of meters per second (22 mph or more), be 140 meters (460 ft) deep, and destroy any structures in their path. A lahar is a volcanic mudflow or debris flow. Lahars have the […]
About S.M.Mirkazemian سید مجید میرکاظمیان
I am an Iranian geologist. I have a master's degree in geoscience (Tectonics) and now as an Engineering geologist, I am working for a road construction consulting company.
I was born in Tehran at 1980. The first my interest to nature was revealed in childhood mountain climbing. During high school I was familiar with geology science and I become enthusiastic. During college, this interest got excessed which was led to the periodical publication of the first geo science whose named “Pezhvak Danesh” (Science Echo) with the help of some of my friends. My scientific online activities were started at this time. I published “Earth” blog in 2002 which helped to answer my and other students of geo science questions regarding to writing, translating and presenting geology contents.my interest in landscape photography and its beautiful views was started in my childhood with an analogue “Zenith 122” camera, got flourished. With my scientific growth and interest in scientific geology photography.
During getting MSc. degree, my work experience was started with teaching in a high school. My next job was in “Sub surface geology department” of Exploration management in “NIOC” (National Iranian Oil Company). After that I continued my experience in “NGDIR” (National Geoscience Database of Iran) subset of Geological Society of Iran. In Military Service, I worked for “Geotechnical laboratory” at Department of Buildings and installations of Army of the Islamic Republic of Iran.
From 2008, I am working for “Iran Oston Consultant Engineers Company” (IOCE) as Geologist and I got involved and helped 14 road projects. Also I cooperated more than 8 studies of large scale geological plans and other some same projects.
Now, I’m member of “IME” (Iranian Mining Engineering Organization) and I published some articles and have some in process.
At 2016, according to shortage of “Geotourism data” about Iran and also the need for introduction of natural traits and geological effects of Iranian plateau, I started up “Zamin Gasht” (Geo Tour) website with some of interested friends.

In geology a bed is the smallest division of a geologic formation or stratigraphic rock series marked by well-defined divisional planes (bedding planes) separating it from layers above and below. A bed is the smallest lithostratigraphic unit, usually ranging in thickness from a centimetre to several metres and distinguishable from beds above and below it. Beds can be differentiated in various ways, including rock or mineral type and particle size. […]
The Mila Formation is one of the Cambrian formations in Alborz. The Mila Formation has 5 measurable members in type section (Mila Kuh, Damghan City). This formation overlies conformably the Early Cambrian Lalun Formation and underlies disconformably the Early Devonian red conglomerates. But on the Chalus road in Central Alborz, four members of this formation […]
Alborz (Persian: البرز), also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the Aladagh Mountains in the northern parts of Khorasan. This mountain range is […]
The Star Valley, which is called “Estareh Kafteh” in local dialect, is one of the most important erosional phenomena in Iran. this valley is located in south east of Qeshm Island in Persian Gulf. In this valley there is variety of geomorphological phenomena which shaped several interconnected branches of small valleys. Besides the mechanical erosion […]
Chahkuh Gorge is located in the northwest part of the Qeshm Island, near West Chahu village. This Geosite is a good example of running water erosion and formation of a canyon form valley. The erosion was the secondary parameter to create this valley; it was happened along a deep joint and crack resulting the Salakh […]
Namakdan cave is among the most important geosites in the Qeshm Island Geopark (Hormozgan province, Iran). The salt dome (diapir) of Namakdan is a unique structure in the Island including several outstanding structural, mineralogical, erosional and sedimentary sceneries. In this Geosite the world record Namakdan Cave exists, the world longest salt cave, 6500 meters. The […]
The Oligocene–Miocene Asmari Formation of the Zagros Basin is a thick sequence of shallow water carbonate. Asmari formation is the youngest and most important reservoir rock of the zagros Basin in the south-west of Iran. The Asmari formation has been divided into two members: one is the Sandstone Member of Ahwaz in the south-west of the […]
Gurpi formation is one of the formation in the Folded Zagros. This formation with bluish-green color consist of alternation of marl and grey shale with intercalations of thin bedded limestone. This formation also has two limestone members so called “Emam Hasan” and “Seymareh”. “Emam Hasan limestone member” consist of fine grained limestone, with thick bedded and […]
Qezel ozan river is one of the longest rivers of Iran that originate from the Zagros mountain range in Kurdistan and East Azerbaijan provinces. Along the way of Qezel ozan, “Hyrochay”,”Zanjanrood” and “Shahrood” are added to it and arrive to Manjil Dam Lake. From the dam site to the Caspian Sea, the river is called […]
