The chemical and isotopic compositions of Precambrian Fe-rich chemical sedimentary rocks
have figured prominently in discussions on the Fe biogeochemical cycle and redox …

In recent years, lanthanides (Ln) have become an object of active studies by soil scientists
and geologists, which is favored by the development of instrumental equipment. It has …

We present experimental results on the sorption behavior of rare earth elements and yttrium
(REY) on precipitating manganese (hydr) oxide in the presence of the biogenic siderophore …

Abstract Rare Earth Elements and Yttrium (REE+ Y) distribution in authigenic phases are
frequently used as proxies for reconstructing past seawater conditions. Sedimentary apatite …

Algoma-type banded iron formations (BIF) are chemical sedimentary rocks characterized by
alternating layers of iron-rich minerals and chert that are generally interstratified with …

The genesis of the Bayan Obo REEs deposit has been debated for a century. The most
outstanding issue concerns the genesis of the ore-hosting dolomite and the contribution of …

The titanium-rich bauxite horizon of the Kanigorgeh bauxite (northeast of Bukan, NW Iran) is
a part of the globally significant known Irano-Himalaya karst bauxite belt. This bauxite …

In China, bauxite is mainly of the karst type. Karst bauxite deposits in Central Guizhou are
widely distributed in the Qingzhen, Xiuwen, and Zunyi districts. The Xiaoshanba deposit is …

In order to better constrain the evolution and petrogenesis of pegmatite, geochemical
analysis was conducted on a suite of apatite crystals from the Altay Koktokay No. 3 …

Sedimentary phosphorites are important carriers of Rare Earth Elements and Yttrium (REE+
Y). Primary biogenic and sedimentary apatite contain very low amounts of REE+ Y and …
