1  ADRIANI 2015 search for relatively light quark matter with charge $\mathit Z$ = $1 - 8$. See their Figs. 2 and 3 for flux upper limits.
2  AMBROSIO 2000B searched for quark matter (``nuclearites'') in the velocity range ($10^{-5} - 1)~\mathit c$. The listed limit is for $2 \times 10^{-3}~\mathit c$.
3  ASTONE 1993 searched for quark matter (``nuclearites'') in the velocity range ($10^{-3} - 1)~\mathit c$. Their Table$~$1 gives a compilation of searches for nuclearites.
4  AHLEN 1992 searched for quark matter (``nuclearites''). The bound applies to velocity $<2.5 \times 10^{-3}~\mathit c$. See their Fig.$~$3 for other velocity/$\mathit c$ and heavier mass range.
5  NAKAMURA 1991 searched for quark matter in the velocity range ($4 \times 10^{-5} - 1)~\mathit c$.
6  ORITO 1991 searched for quark matter. The limit is for the velocity range ($10^{-4} - 10^{-3})~\mathit c$.
7  LIU 1988 searched for quark matter (``nuclearites'') in the velocity range ($2.5 \times 10^{-3} - 1)\mathit c$. A less stringent limit of $5.8 \times 10^{-11}$ applies for ($1 - 2.5){\times }10^{-3}\mathit c$.
8  BARISH 1987 searched for quark matter (``nuclearites'') in the velocity range ($2.7 \times 10^{-4} - 5 \times 10^{-3})\mathit c$.
9  NAKAMURA 1985 at KEK searched for quark-matter. These might be lumps of strange quark matter with roughly equal numbers of ${\mathit {\mathit u}}$, ${\mathit {\mathit d}}$, ${\mathit {\mathit s}}$ quarks. These lumps or nuclearites were assumed to have velocity of ($10^{-4}-10^{-3})~\mathit c$.
10  ULLMAN 1981 is sensitive for heavy slow singly charge particle reaching earth with vertical velocity 100$-$350 km/s.
