    Electron microprobe dating of lunar zirconolite by Changkun Park, Hwayoung Kim

    Published 2024-03-01
    “…In this study, we analyzed zirconolites in a granitic clast of the lunar meteorite DEW 12007 using an electron microprobe. MAN (mean atomic number) background, peak interference, and blank corrections were applied to 31 elements including U, Th, and Pb, and REEs, to obtain high-precision and high-accuracy chemical data of the zirconolites. …”

    Was the moon magnetized by impact plasmas? by Oran, Rona, Weiss, Benjamin P, Shprits, Yuri, Miljković, Katarina, Tóth, Gábor

    Published 2022
    “…The crusts of the Moon, Mercury, and many meteorite parent bodies are magnetized. Although the magnetizing field is commonly attributed to that of an ancient core dynamo, a longstanding hypothesized alternative is amplification of the interplanetary magnetic field and induced crustal field by plasmas generated by meteoroid impacts. …”

    Cosmic Transmission of Periodontal, Cardiovascular and Kidney Disease via Nanobacteria by Jafar Kolahi

    Published 2011-04-01
    “…Unbelievably nanobacteria-like rods observed at the surface of the Tataouine meteorite and Martian rock.The hypothesis: It seems logic to hypothesize that aliens from inner space, nanobacteria, can bring us new disease such as periodontal, cardiovascular and kidney diseases via space travels or meteorites or interstellar dusts.Evaluation of the hypothesis: The main criticism with this idea is how NB can keep alive during transfer among seriously life threatening condition in interstellar space. …”

    A Search for Magnetized Quark Nuggets (MQNs), a Candidate for Dark Matter, Accumulating in Iron Ore by J. Pace VanDevender, T. Sloan, Michael Glissman

    Published 2024-01-01
    “…Indirect evidence of MQNs has been previously inferred from observations of magnetars and of non-meteorite impact craters. It is shown in this paper that MQNs can accumulate in taconite (iron ore) and be transferred into ferromagnetic rod-mill liners during processing of the ore. …”

    Assessing the shock state of the lunar highlands: Implications for the petrogenesis and chronology of crustal anorthosites by Pernet-Fisher, JF, Joy, KH, Martin, DJP, Hanna, KL

    Published 2017
    “…To investigate how plagioclase trace-element systematics are affected by moderate to weak shock (~5 to 30 GPa) we couple REE+Y abundances with FTIR analyses for FAN clasts from lunar meteorite Northwest Africa (NWA) 2995. We observe weak correlations between plagioclase shock state and some REE+Y systematics (e.g., La/Y and Sm/Nd ratios). …”
