Plant fossil remains from the Bajocian–Bathonian of Hojedk Formation, Babhutk area, Kerman, Iran

The first occurrence of Phlebopteris dunkeri and P. woodwardii (Matoniaceae) from the middle Jurassic of Iran

“…According to the plants identified from the Hojedk Formation and their inferred palaeoecology and also the presence of coal-bearing layers, it seems that the Hojedk Formation was deposited under a relatively warm and humid climate. This agrees with previous interpretations based on plant macro-remains from this formation (e.g., Ameri et al 2014).…”

“…The coal horizons of the Middle Jurassic Hojedk Formation of East-Central Iran are fossiliferous, comparable to the Shemshak Group/Formation in the Alborz Mountains in North Iran. The Hojedk Formation is known for containing diverse assemblages of plant fossils (e.g., Vassiliev 1984;Poole and Mirzaei-Ataabadi 2005;Ameri et al 2014). It is Bajocian-Bathonian in age, based on ammonites (e.g., Seyed-Emami et al 2004) and plant fossils (e.g., Vassiliev 1984;Kirchner 1996, 1998;Poole and Mirzaei-Ataabadi 2005;Ameri et al 2014).…”

Additionally, the plant-bearing successions of this formation were dated palynologically as Middle Jurassic (Arjang 1975).…”

Rare earth element geochemistry of coals from the Mazino Coal Mine, Tabas Coalfield, Iran

“…The thickness of these coal layers varies from 0.5 to 15 m. During the last decades, several investigations involving geology, drilling, and even palynology were performed in order to study the relationship between coal-forming environments and coal properties in the Tabas coalfield, but published data about Mazino coal deposit is limited (Yazdi and Golzar 2012). Mazino is the biggest thermal coal deposit in Iran, and geological studies have shown that the coals of Mazino deposit are mainly anthracite to semi-anthracite and (Bragin et al 1981), b Stratigraphy of Hojedk Formation (Ameri et al 2013) dominated by macerals of the vitrinite group with relatively low amounts of inertinite macerals and low volatile matters. The dominant mineral of these coals are pyrite, siderite, ankerite, calcite, gypsum, barite, illite, and clays consisting of argillite, kaolinite, and montmorilinite (Yazdi 2007).…”
