The southwest Sabzevar basin situated in the Sabzevar zone is considered to be an attractive metallogenic province in Iran that hosts both volcanogenic massive sulfide (VMS) and stratiform manganese deposits. The Nudeh Besshi-type VMS deposit is located in the Lower Late Cretaceous volcano-sedimentary sequence. The ore mineralization in this deposit is hosted in the alkali olivine basalt flow and tuffaceous silty sandstone rocks. The Nudeh VMS deposit consists of 2 million metric tons of Cu-Zn massive sulfide overlying a Cu-Fe-rich stringer. The massive sulfide orebody consists dominantly of pyrite, chalcopyrite, friedrichite, magnetite, and sphalerite, together with minor quartz, chlorite, and sericite. Chloritization, silicification, and sericitization are the main wall-rock alteration types; alteration intensity increases towards the stringer zone. Chloritized footwall rocks extend up to 20 m below the stringer zone. The quartz-bearing stringer veins also contain pyrite, chalcopyrite, magnetite, and bornite. Magnetite crystals from the stringer ores show variable contents of many elements, such as MgO (0.05 wt%), Al₂O₃ (0.63 wt%), TiO₂ (0.07 wt%), V₂O₃ (0.045 wt%), SiO₂ (0.65 wt%), CoO (0.10 wt%), NiO (0.009 wt%), ZnO (0.023 wt%), and CaO (0.03 wt%). The moderate to high V contents are interpreted to result from relatively reduced, seafloor hydrothermal activiy. Compositional variations of magnetite are possibly related to variations in oxygen fugacity, temperature, and water/rock interaction. Within the stringer zone, chlorite 2 (Chl-2) in the vein-veinlets and chlorite 1 (Chl-1) in the chloritized alkali olivine basalt rock are chemically indistinguishable, with 26.92–34.67 wt% FeO and 5.99–14.01 wt% MgO. Chlorite geothermometer studies indicate crystallization formation temperatures of 414 °C (Chl-1) and 303 °C (Chl-2), respectively.

位于Sabzevar区域的西南Sabzevar盆地被认为是伊朗一个有吸引力的成矿省，拥有火山成因的大块硫化物（VMS）和层状锰矿床。Nudeh Besshi型VMS矿床位于晚白垩世火山沉积序列中。该矿床的矿石矿化主要存在于碱性橄榄石玄武岩流和凝灰质粉质砂岩中。Nudeh VMS矿床由200万吨的Cu-Zn块状硫化物覆盖在富含Cu-Fe的纵梁上。块状硫化物矿体主要由黄铁矿，黄铜矿，弗里德里希铁矿，磁铁矿和闪锌矿以及少量石英，绿泥石和绢云母组成。绿化，硅化和绢云母化是主要的围岩蚀变类型。改变强度向纵梁区增加。彩色的下盘壁岩石在纵梁区下方延伸达20 m。含石英的纵纹矿脉还包含黄铁矿，黄铜矿，磁铁矿和褐铁矿。纵梁矿石中的磁铁矿晶体显示出多种元素的含量可变，例如MgO（0.05 wt％），Al₂ O ₃（0.63 wt％），TiO ₂（0.07 wt％），V ₂ O ₃（0.045 wt％），SiO ₂（0.65重量％），CoO（0.10重量％），NiO（0.009重量％），ZnO（0.023重量％）和CaO（0.03重量％）。中等含量到高含量的V被解释为是由于海底热液活性相对降低所致。磁铁矿的成分变化可能与氧逸度，温度和水/岩石相互作用的变化有关。在纵梁区内，脉状小孔中的亚氯酸盐2（Chl-2）和氯化碱橄榄石玄武岩中的亚氯酸盐1（Chl-1）在化学上是无法区分的，其中FeO为26.92–34.67 wt％，MgO为5.99–14.01 wt％ 。亚氯酸盐地热仪研究表明，结晶形成温度分别为414°C（Chl-1）和303°C（Chl-2）。
