Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Modified Gravity and Cosmology

The status of experimental tests of general relativity and of theoretical frameworks for analyzing them is reviewed and updated. Einstein’s equivalence principle (EEP) is well supported by experiments such as the Eotvos experiment, tests of local Lorentz invariance and clock experiments. Ongoing tests of EEP and of the inverse square law are searching for new interactions arising from unification or quantum gravity. Tests of general relativity at the post-Newtonian level have reached high precision, including the light deflection, the Shapiro time delay, the perihelion advance of Mercury, the Nordtvedt effect in lunar motion, and frame-dragging. Gravitational wave damping has been detected in an amount that agrees with general relativity to better than half a percent using the Hulse-Taylor binary pulsar, and a growing family of other binary pulsar systems is yielding new tests, especially of strong-field effects. Current and future tests of relativity will center on strong gravity and gravitational waves.

The Confrontation Between General Relativity and Experiment

Cosmology and the fate of dilatation symmetry

Is (ge − 2) apparatus-dependent?

In this paper we discuss experiments testing gravity in space and at ultrashort distances. We show that the proposed STEP experiment has sufficient sensitivity to test how gravity couples to neutrinos and to higher-order weak interactions. Then, after briefly reviewing the recent interest in ultrashort distance gravity experiments, we describe a preliminary round of atomic force microscope (AFM) experiments which utilize the ‘iso-electronic effect’. Our experimental results set new limits on proposed gravity-like forces over distance ranges ∼1–4 nm.

Testing gravity in space and at ultrashort distances

The recent data on ..nu../sub mu/p..--> nu../sub mu/p are examined from the point of view of discriminating among models of the space-time structure of the neutral weak current. The value of the total cross section appears to exclude pure S,P from the interaction and we describe tests to confirm this conclusion. (AIP)

Experimental constraints on strangelets and other exotic nuclear matter

Recent reports of periodic fluctuations in nuclear decay data of certain isotopes have led to the suggestion that nuclear decay rates are being influenced by the Sun, perhaps via neutrinos. Here we present evidence for the existence of an additional periodicity that appears to be related to the Rieger periodicity well known in solar physics.
