Titaniferous-Vanadiferous, Magnetite-Ilmenite …

Titanium or vanadium metals or their alloys are important industrial metals/alloys. Because these resources are in short supply, the investigation of potential titaniferous-vanadiferous deposits needs special attention to bridge the supply-demand gap. The study integrates geological, geochemical, remote sensing, and geophysical data for assessing the …

Orthomagmatic Mineral Deposits | SpringerLink

Titanian magnetite consists of magnetite as a host crystal that contains exsolution lamellae of ilmenite, ulvöspinel and/or spinel. Commonly, ilmenite is derived from initially exsolved ulvöspinel (Sect. 7.2). The Fe-Ti oxide ore is typically hosted by anorthosite, whereby two different geological settings can be distinguished:

Magnetite | Common Minerals

Ilmenite is a dense, black metallic mineral that, when rubbed across a rough hard surface, exhibits a black streak similar to that of magnetite. As ilmenite is not magnetic, a magnet can be used to distinguish pure samples of the two. Some ilmenite samples appear weakly magnetic, however, due to inter-grown magnetite crystals.

Ilmenite is one of the most significant ores of the metal titanium. It is mined as an important industrial mineral in several deposits throughout the world. Many of those deposits are in heavy placer sands. Ilmenite is very similar in structure to Hematite, and is essentially the same as Hematite with roughly half the iron replaced with titanium..

The magnetite-series and ilmenite-series granitoids in Chile.

Paleozoic and Mesozoic-Cenozoic granitoids of the Chilean Andes were studied magnetically in the area between Latitude 22-35•KS. The Paleozoic granitoids are found to be composed of the ilmenite-series and weakly magnetic magnetite-series, whereas all the Mesozoic-Cenozoic ones appear to be the magnetite-series. Lack of significant sulfide …

Evolution of Fe-Ti oxides within the Tiechagou

At the Tiechagou carbonatite, two distinct types of carbonatites are observed, which are the calcio-carbonatite and magnesio-carbonatite (Fig. 2 A-F).The calcio-carbonatite dominantly consists of calcite, magnetite and olivine with accessory apatite, ilmenite, dolomite, biotite, pyrite, chalcopyrite and humite (Fig. 2 B-C, E).The magnesio-carbonatite is dominated …

Ilmenite

Blåfjell mine, Rogaland, Norway. The sample is from an abandoned mine, but not far from Blåfjell is a working Tellenes mine (picture below). Width of sample 13 cm. Another aspect that separates it from magnetite is the crystal structure. Magnetite is an isometric mineral, it forms double pyramids (octahedrons) just like diamond.

Ilmenite | Geology Page

Ilmenite crystallizes in the trigonal system. The ilmenite crystal structure consists of an ordered derivative of the corundum structure; in corundum all cations are identical but in ilmenite Fe 2+ and Ti 4+ ions occupy alternating layers perpendicular to the trigonal c axis. Containing high spin ferrous centers, ilmenite is paramagnetic.
