Abstract
The Sargule Formation was deposited during the Middle Jurassic, representing one of the most important source rocks in Iraq and surrounding areas.
 Jurassic successions are commonly exposed as an isolated patch at some eroded anticline’s cores and limbs in the High Folded Zone, Imbricate Zone, and Thrust Zones of northern Iraq. The Sargelu section is located in Sargelu village at Surdash anticline, while the Rania section is located in Rania city near Hanjira village at Shaweri anticline. Fieldwork in Rania and Sargelu Sections allow to divide Sargelu Formation lithostratigraphically into many subdivisions as follow:
 The Sargelu Formation in the Rania section is about 40 m and can be divided into two lithologic units; the upper thin to medium bituminous limestone beds alternated with thin chert beds, and the lower thin to medium bituminous limestone beds alternated with fissile gray shale beds.
 the The Sargelu section comprises 180m and is divided into three units; the upper unit consists of dark gray limestone beds and thin brownish-black of laminated shale. The middle unit includes dark chert alternated with dark gray bituminous limestone and brownish-black laminated shale. At the same time, the lower unit consists of dark gray bituminous limestone beds alternated with medium brownish-black laminated shale beds.
Highlights
Sargule Formation was deposited during the Middle Jurassic which represents one of the most important source rocks in Iraq and surrounding areas
The lithostratigraphy of the Sargelu Formation was studied at Rania and Sargelu sections
Field observation and the correlation cross section (Fig.13) revealed the following: The thickness of the Sargelu Formation in the Rania section is 40 m which is divided into three lithologic units
Summary
The Sargule Formation (Middle Jurassic) represents one of the most important source rocks in Iraq and surrounding areas. They are located within the Sulaimaniya governorate in northeastern Iraq. The first section is bounded by latitude (35°52′2.0′′) North, and longitude (45°09′ 49.0′′) East near Surdash village 180 m thick while the second section with a thickness of 40 m lies within latitude (36°17′11.8′′) North, and longitude (44°51′ 17.2′′) East near Hanjira village 2km northwest of Rania town (Figure 1). The studied area covers two Sargelu Formation outcrops The first section is bounded by latitude (35°52′2.0′′) North, and longitude (45°09′ 49.0′′) East near Surdash village 180 m thick while the second with a thickness of 40 m lies within latitude (36°17′11.8′′) North, and longitude (44°51′ 17.2′′) East near Hanjira village two km north-west of Rania town (Figure 1). This study aims to summarise the field observation and lithostratigraphic study of the Sargelu Formation in Rania and Sargelu sections
