Limonite Sandstone s Athleticus s Sandstone, ocher brown and deep brown, slatey, coarse, The regression isnt in relation to the width of the really dry area, was limited to the edge area, but its effect on the sediments was regional as a result of the reduction in the height of the water column above it The MonotisDactylioceras bank is an excellent fossilized record of events
Final product is hematite or limonite. Sandstone quartz grains are highly resistant to weatheringgy and are recycled into new sand deposits cement type, calcite, iron oxide,,, or silica, controls erosion of sandstones. Limestone weather
In all, limonite ore shows a codoping effect with multisite occupation thanks to its multielement content. In this regard, the present study discusses the potential use of limonite ore as both an alternative iron source and a multielement doping agent in the field of LLZO synthesis in terms of the microstructurepropertyperformance relationship.

As observed above, the darkening of quarry samples when irradiated in dry condition is associated with the selective removal of calcareous cement, including the pigmenting limonite. The final effect is a darkening because after the removal of the surface cement the main component of the natural stone colour appears through the filtering action of the semitransparent grains of quartz and
Limonite / l a m n a t / is an iron ore consisting of a mixture of hydrated iron III oxidehydroxides in varying composition. The generic formula is frequently written as FeO OH n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.
Lithological Description: White, buff, yellow, orange and red to dark brown, generally unconsolidated fine to mediumgrained sand, with seams and irregular masses of limonitecemented sandstone and rare siliceous or calcareous concretions, localized beds of grey to white silt and clay or mudstone, and rare ooidal limonitic ironstone.
Sandstone also commonly known as arenite is a clastic sedimentary rock composed mainly of sandsized minerals or rock grains of about 0.05mm to 2cm, matrix, cement and pore space. figure 2 . . . Figure 2: A microscopic photograph of a Nubia sandstone under the polarizing microscope. It is composed of entirely of monocrystalline, subrounded
Ironrich sedimentary rocks are sedimentary rocks which contain 15 wt. or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian 3800 to 570 million years ago , the early Paleozoic 570 to 410 million years ago , and the middle to late Mesozoic 205 to 66 million years ago .

Limonite ore is from Torobulu, Southeast Sulawesi. In the first step, limonite, sodium sulphate, and graphite were sieved by a shaker sieve until reaching a size of 100 mesh, which is the optimal size for laterite and were weighed for 50 g for limonite and mixed with 5, 10, and 15 Na 2 SO 4 and the variation of stoichiometry calculation 0.125, 0.25, 0.5, 1 equilibrium condition , and 1.5
Limonite is named for the Greek word /le.m n/ , meaning quotwet meadowquot, or /lm.n/ , meaning marshy lake as an allusion to its occurrence as bog iron ore in meadows and marshes. In its brown form it is sometimes called brown hematite or brown iron ore..
