Magnetic anisotropy of limestones from Limhamn, Southern ...

高达12%返现  The magnetic fabric of the Limhamn limestones is characterized by a low initial magnetic susceptibility. Of 68 specimens with a positive susceptibility, 10 show a distinct anisotropy. In nine of these, the axes of minimum susceptibility are practically normal to the magnetic foliation plane. The observed anisotropy pattern has some resemblance to a magnetic fabric acquired by deposition

高达12%返现  The Maastrichtian and Danian limestone sequence known from Limhamn (southern Sweden) contains ferromagnetic minerals dispersed in a diamagnetic matrix. The initial magnetic susceptibility measured does, on the whole, agree with the iron amounts registered by X-ray. The aluminium contents indicate that the magnetic minerals are of terrigenous origin.

Investigation of rocks with low remanent magnetization ...

Mar 01, 1992  A 290 m sequence of Maastrichtian and Danian limestones from Limhamn, southern Sweden, has been investigated magnetically. The observed mean natural remanent magnetization is 24 μ A m -1 . The remanent magnetization is carried by pseudo-single-domain or single-domain magnetite particles, and was observed by various rock magnetic methods.

Magnetic anisotropy in the Trenton Limestone: Results of a ...

The magnetic fabric of a collection of Trenton Limestone specimens has been determined using this method, as well as by conventional anisotropy of magnetic susceptibility. The results demonstrate the usefulness of the new method for finding the magnetic fabric of rock units such as the Trenton in which the bulk magnetic susceptibilities are low.

Magnetic properties of marine limestones - Lowrie - 1982 ...

The magnetic minerals most commonly identified by these techniques are magnetite, goethite, hematite, and maghemite. These magnetic minerals occur in different combinations in the marine limestones of central Europe and the Mediterranean realm. Pyrite is common in certain limestones, where it can be the precursor of an unwelcome late goethite.

Jan 01, 1997  It is sensitive to small modifications of the magnetic fabric (Sjoberg, 1992). The whole Askersund granite-gneiss complex contains large K -feldspar phenocrysts and has developed during a long cooling time. In the central part the phenocrysts are generally spheroidal, becoming more ellipsoidal towards the periphery.

Dec 27, 2002  The magnetic anisotropy for chlorite, muscovite and biotite specimens were measured at room and 77°K temperature . These three phyllosilicates have similar anisotropy degree (K max /K min) at room temperature (small dots), but the magnetic anisotropy degree at 77°K is increased due to the disproportionate growth of K max and K min (large dots).

Dec 01, 2017  The K-T boundary claystone, which is composed of kaolinite and small amounts of illite/smectite mixed-layer clay, is similar in most respects to kaolinite tonstein layers in coal beds. At some, but not all, K-T boundary localities, the boundary claystone contains solid kaolinite and hollow and solid goyazite spherules, 0.05 to 1.2 mm in diameter.
